In Rush's defense (I can't believe I just wrote that), Rush hasn't endorsed anyone. Several weeks ago, he though it would be fun and amusing for entertainment purposes to get under Huckabee's skin. He has been going about McCain for some time now. Rush never in a hundred years ever thought they would be the only ones left on the ballot, as he painted himself and his audience into a corner.
It is not Rush’s fault. It is all in the hands of the voter. The American voter is the problem.
