"Such as challenging the Electoral College vote even though Bush won Ohio by 119,000 votes? By putting words into Condi Rice's mouth? "
While I don't agree with those decisions I don't think these are necessarily 'unprincipled' things to do. What I do have a problem with in politics is all of the backroom dealing, which the Clintons have made careers on. I don't have a problem with political opponents as long as they are upfront. At least you know what you're dealing with.
Sorry, but Boxer sliming Condi was hardly upfront. Boxer is a snake, pure and simple.
