Liberals hate Bush because he was particularly bad even for a Republican. He's a war criminal who started a war for no good reason.
Republicans hate Obama like they would hate any generic Democrat. The conspiracy theories they believe about him may be tailored to his particular race but they will believing similar ridiculous things about the next Democratic president.
Question (I'm legitimately curious):
Would you have the same impression of why conservatives dislike him if he were the same President and race, but his name was Barry Smith?
I'm not sure what point you are trying to make. You should just make it yourself rather than try to trick me into making it for you by asking loaded (?) questions.
Actually, I wasn't trying to be tricky at all. I was just asking whether you thought it had more to do with his race (African-American) or his name (Muslim sounding). Of course, I think 95% of conservatives are opposed to him because he is a liberal Democrat.
I think it's because his dad's from Kenya. If his dad was a Black dude from America,there obviously wouldn't have been Birtherism.
