That could be true and I'm not saying you're wrong. In my opinion though, there are plenty of independents out there (and Hillary supporters) who are not sold on Obama and are looking for an excuse not to vote for him. Its why Rev Wright, the flag pin, and the pledge were such big stories.
Let's be honest....the economy blows and Bush has done nothing to defend himself and never has. Obama should be killing McCain in the polls, this shouldn't even be a close race. But that's not what's happening, and if you listen to any of the pollsters its that Obama can't close the deal and people have doubts about him. Gallup said that they expect the race to tighten again after the economy bump Obama is in right now. All these issues I mentioned above do have an effect, even if we think they shouldn't. That's the drawback of Obama not being well known enough. Same goes for Palin.
Again, you can disagree, it's just what I see happening.
