Why doesn't anyone have any reason of substance not to vote for Obama?

How about his lack of experience in politics? His proven personal choices for ociation in a racist church? His proven lies and instability? A poor voting record? These are all arguments that can be verified through impartial research, and that have all been presented on this site as well. I don't know my stance on candidates yet, but these are the issues. My personal question, why do people support him based on the proposed "radical" changes, when a majority of his claims won't make it through congress anyway?
