Well, by the looks of this board, and the number of bumper stickers I see, it looks like the Obama supporters will be happy come November.
But there is one thing you have to keep into account.
There are sharks in the water. Hillary Clinton is still out there, and she just may torpedo Obama's campaign just like she torpedoed John Kerry.
But you live in a blue state. I was in Texas and Arizona recently and I've never seen so many Nobama/pro-McCain bumper stickers in my life. I went to this little pro shop while I was in Texas to pick up some strings and stuff, I had on an Obama t-shirt and the stringer says "He's a Muslim, why would you vote for a Muslim for president in our country?" Some people are hopeless. 
Anyhow the democrats have out registered republicans the past few years and Obama's ground game is pretty massive, but given this country's recent voting record, it would not surprise me if he doesn't win. A lot of people just aren't "comfortable" with Obama.
I'm not really comfortable with Obama either, but it has nothing to do with the Muslim rumors.
I can understand the Muslim statement, a lot of people vote because of race, religion or some other factor they think is important. I think many blacks will vote for Obama because of race, not a good reason in itself but will make up reasons to justify the decision.
Normal behavior for humans is to gravitate toward what is familiar.
So that's it? Just give in to your urges and go with what is familiar? What makes us any different than dogs? Human beings have the unique ability to reason, to rationalize to seek answers,to reflect. We have a level of self-awareness unlike any other species. That self-awareness allows us to question our motives, our intentions, our beliefs, our surroundings. We have the ability to enlighten ourselves, to look deeper into ourselves and others. To prejudge is a natural human condition, yes, it's our survival instinct. We tend to group things(and of course people) together and assign either positive or negative qualities to them. But again we have the ability to look deeper if we choose to do so.
Place an apple on the table and we can choose to see it as just another apple or we can attempt to discern what kind of apple it is. A red delicious, granny smith, big, small, sweet, tart, bland. We can reflect on what makes that particular apple different from other apples simply by choosing to look deeper. It's all about choices. So I'm not going to buy the "it's natural to be a bigot" argument for not voting for a particular candidate. That's a choice, you choose to be a bigot. You choose not to enlighten yourself, you choose to give into your baser impulses. Don't blame it on your species.
