At least not openly / overtly. Sadly, there are many in the US who cannot see beyond his skin color .....
It's really quite simple. If someone disagrees with Obama or doesn't support Obama, they're racist, at least in the liberal viewpoint. If Obama loses the election, it will also be because of race/racism NOT because of his substance or positions.
Many examples of this have come up, like from John Lewis:

And now most recently from a Kansas City Star article:

Did you guys know that it's an old code word for black to call someone a socialist?
The fact is Obama and Biden have made some startling comments, which they cannot hide from. The only way to defend themselves now is to pull out the race card.
Just for the record, if there was a Black Republican running in the primaries last year, that had similar viewpoints to McCain, I would have picked him over McCain. I understand why loads of people are excited about Obama, from a historical perspective. I too would love to put a minority in the White house and make history, if their positions and views matched with mine. OBAMA DOES NOT FIT THE MOLD. It's not because he's only 50% Black. It's not because the 50% Black he is, comes from Kenya. It's because of his substance and his positions! It's because his beliefs of what is best for this country clash and are counter to my beliefs. That HAS ALWAYS BEEN THE REASON.
Another thing I don't get about the race argument is if I'm some racist bigot, then why in 2004 did I vote for Bush over Kerry? Both are "White" correct? It's just nonsense. To be honest from my experience I have found racism coming from the other direction. I was in one of the main walkways of my Campus the other day for a bake sale and an Obama supporter (also the President of Student Organizations) was spouting the most ridiculous comments, (paraphrasing here): "I'd gather all the Christians into a room and drown them". "Those white people must be embarrassed of McCain after that debate".
I'm seriously thinking about doing a documentary at my school on the craziness of Obama followers.
Lastly I want to ask why is it that violence related to this Presidential contest stems from Obama supporters? There have been several stories on the news where people with McCain/Palin or NOBAMA bumper stickers/yard signs, have had their car or properties vandalized.
