# News A better way of voting

1. Mar 5, 2012

### causalset

Have anyone ever considered the following voting system. Each persion is allowed a TOTAL of one vote. But that one vote can be ''split'' between candidates. So a person can say, for example, that 1/2 of the vote goes to candidate 1, 1/4 goes to candidates 2 and 3, while candidate 4 doesn't get any vote. And thats just an example. A person is allowed to come up with his own way of ''spliting'' his vote however way he chooses. To make his job easier, the numbers he enters will be normalized by the mashine. So, for example, a person can put number 7 next to candidate 1, number 5 next to candidate 2 and number 2 next to candidate 3. Then mashine will automatically say that he gave 7/14=1/2 vote to candidate 1, 5/14 vote to candidate 2 and 2/14=1/7 vote to candidate 3.

I just think this way of voting would allow more accurate assessment of whom people really want to be elected. For example, suppose candidates A and B have nearly the same politics that people favor; on the other hand, candidate C has ''unfavored'' politics. Now, suppose that the politics of candidates A and B are so similar, that people who ''favor'' them have very hard time deciding whom to vote for. So they all decided to pick A instead of B because A is younger and has more energy. As a result, candidate C will do better in the election than candidat B. But that is not an accurate estemation of people's opinion: after all, if A wasn't running, then ALL of the votes for A would have gone to B and B would have won over C by substantial margin. Now, if we have the kind of voting I propose, this would never happen. In this case people would simply split their votes between A and B, hence we would get accurate picture that both A and B are doing better than C.

Now you might ask: wouldn't each individual person be deciding to give ''all'' of his vote to his top choice rather than spliting it, anyway? Well, not necesserely. If a person favors two candidates, he might want to ''cover all bases'' by making sure that if one of them is going to lose, the other would win. That would be a motivation in spliting vote. Or for exaple suppose one of the candidates is Hitler, so our foremost goal is to prevent Hitler from winning, while the choice between other candidates is secondary concern. Well, voting for just ONE person ''other htan Hitler'' might prove to be ineffective if it turns out that that ''one person'' obtained substantially less votes than Hitler did. Thus, the most effective strategy would be to split a vote between all candidates other than Hitler so that if one of them won't win the other will.

Now, of course, what I just said will vary greatly depending on people's awareness of public opinion and so forth. So in some situation people might, in fact, choose to give all of their vote to one person. But still, at least there has to be an option of spliting a vote if someone wants to do that.

It wouldn't work. Bumper stickers aren't big enough. Don't blame me. I voted 2/5 for Romney, 1/5 for Obama, 1/5 for McCain, and 1/5 for Hillary.

### causalset

Doesn't have to be stickers. In fact I think more in line of a computer. I imagine a computer in a voting booth and a person should enter numbers on the keyboards next to candidates. Then when he presses enter key, the numbers are automatically being normalized (thus assuring total of 1 vote) and added to the respective candidates.

Well, if we're going to go 'crazy' on it anyway. Why not a voting system where you don't vote people in, but vote people out?

OP: What specific problem do you think your proposed system solves? It seems to me like it's a whole bunch of extra complexity with no useful advantage. People can just decide which candidate they prefer, and vote based on whatever system they use to weigh their decision.

There is no practical benefit to knowing the actual popularity of the unpopular candidates, is there? All we care about is that the system accurately select the most (electorally) popular candidate. Your proposal might alter the vote tallies so they more accurately tell you who was more popular among the losers, but it still produces the same winner as the existing system, doesn't it? At least in your above example, it does. Or maybe you can give us an example where it produces a different winner?

PS: Jimmy was making a joke. Bumper stickers are things that people stick on their cars to tell the world something about themselves.

Good idea. Here is how we can accomplish this. Each person can put either positive OR negative numbers next to each candidate. The normalization will be a division by sum of ABSOLUTE VALUES of the numbers a person put. Thus, if there are three candidates, and I put 5 next to A, 7 next to B and -15 next to C, then the normalization constant will be 5+7+15=27; thus, a candidate A will gain 5/27 points, candidate B will gain 7/27 points and candidate C will LOSE 15/27 points.

### causalset

Okay here is an example where it produces a different winner:

1. Democrates would like either A or B to win, without having any strong opinion between one or the other

2. Republicans would like either C or D to win, without having any strong opinion between one or the other

3. If C or D is to win, democrates would prefer that it is C rather than D

4. If A or B is to win, republicans will prefer it is A rather than B

5. Candidates B and D look younger and more energetic than candidates A and C, which slightly tilts vote in favor of the former

Now, if we have ''standard'' voting system, then items 3 and 4 would not affect the election result. Thus, the only factors that would affect results are 1, 2 and 5. The items 1 and 2 have no bearing on (A, C) vs (B, D). The item 5 says candidates B and D are ''better'' in some way. Thus, the president would be either B or D.

On the other hand, if we introduce MY system of voting, then items 3 and 4 will begin to affect the election results as well. In fact, items 3 and 4 will ''outweigh'' item 5. Thus, the president will be either A or C.

Well one example of a problem that it solves is when people can't decide between two candidates. In this case, we don't want a ''random choice'' to have as much effect as well informed decision. So we give them another option: they don't have to flip a coin, they can just split a vote.

That's a better example (#8), thanks. Lunchtime over - will think about it later.

### skeptic2

It would also solve the problem of 3rd party candidates splitting the vote of one of the other parties. Examples: It is likely that the reason George H. W. Bush lost to Clinton was that Ross Perot took more votes from Bush than he did from Clinton. It is also likely that Gore lost to George W. Bush because Ralph Nader took more votes from Gore than he did from Bush. Would Romney be as popular if there were only one real conservative candidate to choose from?

There's no difference between two candidates splitting the votes in the current system and two candidates splitting the vote in your system. If Democrats like candidates A and B, and Republicans like candidates C and D, if the Democrats all split their votes between A and B the Republicans can just all vote for C and make him the winner, even if the population is 3/5ths Democrat and 2/5ths Republican.

It seems like this voting system is designed to solve problems that aren't the problem with our current voting system, namely that voting for someone other than the main Republican or Democrat is a waste - only now you can waste half a vote instead of a full vote

### MarcoD

What are the problems with the US voting system?

14. Mar 5, 2012

### causalset

No, what I said is that in my voting system democrates will be able to help C get ahead of D, despite the fact that both C and D are republicans. This can be done because democrates can use ''bigger'' portion of their votes for A and B, while reserving ''smaller'' portion for C and D, just in case A and B were to lose. This requires vote splitting. After all, each individual democrate cares more about voting for A and B rather than ''what if they are to lose''. So if votes couldn't be split, republicans would be the only ones voting for C and D. While if votes can be split, democrates will vote for C and D as well. Now, if C and D appeal equally well to republicans, while democrates have clear preference of C over D, then the REPUBLICAN candidate C will win due to DEMOCRATE vote, BUT ONLY IF votes can be split.

If you read the example more closely, the republicans have slight preference towards D over C (this is due to their ''indifference'' in part 2 combined with candidate D slight advantage mentioned in part 5). So if republicans are the only ones voting for C and D, then D would be a winner. BUT the democrates have HUGE preference towards C over D. So if democrates can offer fraction of their vote, then the candidate C will win. But their ability to make candidate C win is dependant upon splitting of vote since their top preference is to vote for either A or B.

I would much prefer that the US adopt the instant runoff system, in which voters get to make ranked choices, and the candidate with the lowest vote tally is eliminated between rounds. I believe that would have prevented the election of our Tea-Party governor. He got 38% of the vote, but a majority of voters preferred the Democrat (Libbey Mitchel) or the moderate Independent (Elliott Cutler). The one with the lower vote total would have been eliminated in the first round, and the other would have been inaugurated.

### causalset

Here is the example of a problem. Suppose more people voted for A than for B. But also suppose that people who did NOT vote for A actually hate A, while people who did NOT vote for B are semi-positive towards B but would rather have some other candidate. Now in light of this, it would actually be more fair towards general population to elect B rather than A. This, however, can only be done through split votes. The fact that candidate A is ''hated'' more than candidate B implies that candidate B would receive more fraction-votes from people who would otherwise not vote for him, which would allow him to win.

### causalset

Ranked choices is certainly ''better'' than only one choice, but still ''not as good'' as what I am proposing. Suppose you like nearly the same your top two choices, while you like the third and fourth choice a lot less. In this case, you can not indicate this by merely ranking them; you can, however indicate it by splitting your vote in appropriate way.

The great part about instant runoff is that you don't split your vote. Fanatics wouldn't split their vote anyway, in the hopes of getting their party's candidate into office when other voters split their votes. Indicating ranked preferences increases the chance that you will get a candidate elected that is preferable or at least acceptable to you.

I'm starting to see the arguments for the weighted system, but let's be honest I'm not sure the added complexity and confusion would really bring enough added value.

I think when it comes down to it politicians try so hard to be ambiguous and general these days! if you have two candidtaes they each get about half the vote, if there are three candidtaed they each get about a third of the vote... People vote for whomever they like best on TV regardless!

Sounds like you'd achieve the same result as some existing variations of the Single Transferable Vote scheme.

Try looking up some of these voting schemes, see if you like them;

Gregory method,
Meeks method,
Warren method,
Hare-Clarke method,
Wright method,

and if you are doing internet searches, combine these terms with the words 'Droop quota', and that should pull up the links to these [and other] schemes.
