The GOP is not racist by itself nor is the Tea Party. There are probably a few individuals in these groups that are racist, just as there are racists on the left and in the ACLU. The difference is that the ACLU and the left promotes racism at the government level and the GOP and the Tea Party do not.

The left uses race to deflect from issues. They also depend on race for votes.

Since liberalism is a mental disorder I'll cut you some slack for not being able to figure this out on your own.
