I think it is a seriosu error to try to paint Kerrty witht he same brush as Bush. There are important differences between them.

Kerry does not lie through his teeth obsessively. He is not craven. He does not have Rove, Cheney and Wolfowitz in tow. He does NOT believe, from what he is said, that the Patriot act should be renewed, but rewritten from the ground up. He didn't run away from war, but he knows better than to puruse it mindlessly.

Believe me, in this case Devil B is a better choice.
