Brit Hume actually challenges Paul Ryan -- on everything. Holy Cows! What's going on at Fox? I think they really dislike Romney. Either that or they're trying out journalism.
Also, you'll want to check this, this and this out. It's the explainers and fact checks on the Medicare cuts and why they went to Obamacare. What we have here is Ryan thinking Americans are too stupid to do research, so he tries to be wonky, and then he points out he's on the Romney ticket.
Hume even brings up Ayn Rand. It should be noted that Ryan's voting record is almost the same as Michele Bachmann, which means Ryan = Bachmann.
