DEBATE OPEN THREAD….Kevin had to step away unexpectedly for a day or two, but in the meantime, I thought I’d open the floor for some discussion about the Republican debate at the Reagan library.

Did Romney do anything to slow McCain down? Did McCain do anything to undermine his frontrunner status? Did Huckabee have any success gaining ground? Did Paul get a chance to talk at all?

The floor is yours.

Post Script: For what it’s worth, Arnold Schwarzenegger was in attendance tonight (seated alongside Nancy Reagan), and he’s poised to back McCain.
