You're right -- not sure where I got that impression, sorry.
Regarding the impact, CNN commissioned a poll, which showed a 16% gap in people who said it made them less likely to vote for Romney vs more likely. It would be nice if they did some polls on some of Obama's gaffes last week to see how they stack up. I see the potential for an inherent negative response to even an innocuous question, as simply asking about it implies there's something in the content that should matter to voters. If nothing else, asking a similar question about an Obama gaffe would enable a comparison.

The rule of gaffes:
1) Anything a candidate's opponent claims is a gaffe is worth at least some analysis.
2) Pointing out random gaffes winds up being pointless noise. For the gaffe to have an effect, it has to support some key point a candidate is making about his opponent and there has to be more than one gaffe in the same category. In other words, the gaffes have to fit into some theme; not just be random gaffes that fade into oblivion by the next news cycle.
3) The most significant gaffes are when the message isn't really a gaffe - only the way the message was conveyed. For example - "Instead of raising taxes, we should eliminate tax loopholes that prevent everyone from paying their fair share" followed by "Everyone should pay at least something in taxes". The latter statement indicates which loopholes are going to be closed and reveal whose taxes are going to be "raised". This kind of follows from #2 - the gaffe has to mean something.
Romney's 47% statement fits into the theme that Romney doesn't care about the middle class and the poor, especially when paired with some of his statements about the poor made during the primaries.
Obama's statement at Univision's town hall, "The most important lesson I've learned is that you can't change Washington from the inside, you can only change it from the outside", is certainly a strange statement for a President to make, seeing as how he's about as inside Washington as one can get, but it has to be tied to a theme to actually mean anything. It has to be tied to the inability to get things done, not getting the wrong bills passed, for example.
A lot of tiny holes in a campaign just don't do that much damage. The holes have to be grouped together to make a single hole big enough to do real damage.
And, to be honest, even most of the gaffes that can be tied to a theme won't actually have much effect. You almost have to be lucky and have the gaffe sway some small group of voters that happen to be significant in this particular election. For example, making a gaffe that pushes a few undecided Latinos one way or the other doesn't affect a candidate's overall performance, but does hurt them in Florida, Colorado, and Nevada - states that have chance of being the tipping state, but also may wind up not mattering.
