Yes, Senator Turtle is a thoroughly terrible person who laughs at the idea of solving the fiscal cliff. What else is new?
McConnell wasn't laughing at the idea of solving the fiscal cliff, but that Geithner thought the BS he was peddling would solve it. Problem is, no one wants to go on the record as proposing first the actual spending cuts that will be needed to solve the cliff, so both sides right now are engaged in a game of chicken, insisting that the other layout their spending cut plan first.
