GOP Undercard debate - let it be the last one

Here's my impression of the last two hours:

George Pataki:

:

Mike Huckabee:

Rick Santorum:

Lindsey Graham:

Who Is on the GOP B-Roll?

Not B-Roll

Rumor has it that Rudy Giuliani is considering a 2012 run (Fox News).  Other second tier candidates like George Pataki (Politico), Jeb Bush (Politico) and are seeing their names re-surface or being floated.  With some big and medium-level names like Huckabee, Trump, and Daniels opting out, there is some perceived room for others who might have previously been considered long shots for the 2012 nomination.  But how many of these names are serious, how many are trial balloons, and how many are wishful thinking or just plain crazy?
