Ever-garrulous curmudgeon Barney Frank was memorably expressive during an appearance on MSNBC last night. The high-ranking House Democrat was talking with Rachel Maddow about Standard & Poor's downgrade of US credit, with Frank criticizing rating agencies for claiming mortgage-backed securities were “wonderful stuff” prior to the financial collapse in 2008 when the investments were “crap.” (video clip after page break) Then Frank really cut loose — But with regard to the US budget, they have no special expertise, everybody knows everything. So I am disappointed but not surprised, but the key, Rachel, I think is we have to figure out, all right, what do we do from here and you're right, we got to get some jobs (reverberating sound heard as Frank shifts in seat)
