Maybe.
Well - yes, but that was 40 years ago! I think the primaries count for more these days. I remember the '68 Democratic Convention in Chicago.

Daley's people got a little rough.
The 2008 Democratic National Convention will be the 2008 United States presidential nominating convention of the Democratic Party. It is scheduled to be held from Monday, August 25, through Thursday, August 28, 2008, in
Denver, Colorado. (The 2008 Republican National Convention is planned to start 4 days later, in St. Paul, Minnesota).
Hey, Bob, the 2008 DNC is in your neighborhood. Too bad it's not in Chicago. That would be interesting for Obama.
The primaries count for 80% of the delegate total for Democrats. In other words, one of the candidates has to win a little over 62% of the delegates in primaries/caucuses to wrap up the nomination on the first ballot even if every one of the 796 superdelegates votes for someone else..
Unless you go into the convention with an advantage in superdelegates (unpledged delegates). While the delegates aren't pledged, superdelegates are constantly polled by news organizations and, right now, Clinton is pulling about 60% of the superdelegates while Obama is pulling about 30%. If that holds up, Obama needs to win about 55% of the delegates from primaries and Clinton probably needs about 47%.
Right now, Obama has won 41% of the primary delegates and Clinton has won 39% with Edwards picking up the extra. Either way, with over half of the 796 superdelegates remaining mum on who their voting for, there's going to be quite a bit of suspense going into the convention.
If no one wins on the first ballot, all of the delegates become uncommitted delegates and can vote for whoever they choose (Alabama football coach Bear Bryant finished ahead of Alabama governor George Wallace in the '68 Democratic primary, although neither received enough votes to be more than trivia).
And the total delegates available could increase by around 300 depending on what happens with Michigan and Florida delegates.
For Republicans, the method of selecting delegates is decided by each state. Some are winner take all, some are proportional, and some are a mix. Some are committed by primary or caucus results and some aren't (for instance, Iowa and Nevada haven't selected their delegates in spite of making headlines in the last few weeks - supposedly, the results of the caucuses will sway the results of the state conventions, though).
All in all, nothing like either nomination system would ever pass muster for an actual election. The goal is to keep the nomination system from running amok and having voters nominate some upstart like Ron Paul or Mike Gravel. Party leaders like to give party leadership some control of the process and not relinquish too much power to run of the mill Republican/Democratic voters.
And to think - people complain about the electoral vote.
