Gingrich and Paul were coming in last and dead last in the last several primaries. Levin was steadfast on his conservative stance until Santorum quit. He knows the upcoming states aren't going to go for Gingrich. Newt rode the Food Stamp line in the debate right through South Carolina. His shot was the south and it didn't pan out.
No, the time for all those jerks to go over to Romney, if ever, would have been AFTER THE PRIMARIES ARE OVER AND ALL THE STATES HAVE HAD THEIR SAY AND WHEN AND IF ROMNEY ACTUALLY WERE TO BE NOMINATED.
Not while we still have an ex-speaker of the house and conservative Republican still fighting you Romneybots.
AND NOT A MINUTE BEFORE.
