We agree on much. In my mind, essentially everything you said would indicate a vote for Romney, yet you are voting for Obama because the GOP supposedly embraces anti-intellectualism, bigotry, racism, and supply-side economics.
First, I would ask you to provide concrete examples to support your claims of anti-intellectualism, bigotry, and racism. It sounds like you're simply swallowing whatever the far left dishes out. I will agree that anti-intellectualism is a problem in some GOP circles (namely the evangelical crowd), but I don't think it's a widespread problem. As for claims of bigotry and racism, that's simply bullshit.
Second, I would point out that Romney's tax reform proposal is more Keynesian than Obama's. In Keynesian economics, taxes are reduced during a recession, not increased. Obama isn't even really a Keynesian. He's more like an Don't-know-what-the-hell-I'm-doing-ian.
Ultimately, I would argue that Romney is the best shot at preserving progressive government. With some adjustments, he will save programs that will otherwise go bankrupt. Democrats choose to ignore this problem.
