Alan Grayson Or Patrick Murphy?

The rock-ribbed Democratic establishment has a Boehner for Murphy because he is a perfectly solid right-wing politician, like all establishment Dems.  Grayson is not an establishment guy.  Nope.  He's way too abrasive and normal to ingratiate himself to the guys and gals in charge, but in the Senate, who would be way better for America?  Who would be a better enemy of the teabagging, racist, fucknut Republicans?
