The only people I've seen with McCain bumper stickers are private university kids driving bmw suvs or some similar vehicular display of wealth. I usually prefer to vote third party since having 2 parties in power means corporations only have 2 groups they need to buy-off, but I'll be voting Obama this election because I'm sick to death of the republican party. Additionally, I think it would be great to have a black president. My parents lived through segregation. The 1910's and 20's were dominated by racism to a greater degree than even the years following the civil war. That was only 2 generations ago, a very short period of time when you think about it.
Also, I think with the advent of advanced biotechnology (genetic engineering and bionics), a libertarean vote is a vote for suicide. The government of america, and the planet at large, needs to keep a tight hand on corporations or we will make the same mistakes with the new biological technology as we did with the chemistry and physics driven advances of the last century (pollution, wmd's, cultural upheaval, etc.). The future is closer than you think and I don't want my grandkids to require a microsoft windows platform for their neural interfaces (See Kevin Warwick's research).
Also, the typeface Arial is a rip off of Helvetica.
