538 throwing out a bunch of claims doesn't really prove anything at all does it? Just because they make a bunch of charges that may or may not have any factual basis, the RCP team is obligated to respond?

I'm kind of with Tuff, in that it seems a bit like an up-and-comer trying to throw some mud on a bigger competitor. Just because this guy claims they have intrinsic bias doesn't make it so. He needs to build a better case than that.
