Every week or so, the Republican Presidential Race Clown Car pulls over to let someone crawl out of the back seat to ride shotgun. As always, Mitt Romney stays in the driver’s seat. This week, it was Newton Leroy “Newt” Gingrich, deep into his third or fourth incarnation as a rehabilitated presidential wanna-be, who got to sit in the front seat. He replaced Herman Cain, who was told to go sit in the backseat and keep his hands to himself. It may be telling that Perry, Santorum, Paul, and Huntsman were told to sit between Cain and Michelle Bachmann. Coincidence or is there a message in this?

Let’s hope Newt doesn’t get too comfortable up there. There have been two constants throughout this race: Romney is always the driver and everyone takes turns sitting in the front seat. Santorum, Paul and Huntsman have been whining ever since the last potty stop. At some point, we’re going to have to pull this car over and set a few things straight.
