Newt says he’s staying in the GOP race until the GOP convention in Tampa. His thinking may change if he pulls up third in Alabama and/or Mississippi. Listen to what Gingrich said here.
Look, if it were up to Santorum, he would show Gingrich the door, pronto. Santorum will need to have convincing wins in both Alabama and Mississippi to make a statement.
Meanwhile Romney limps toward the nomination until "Santogrich" (Santorum and Gingrich combined) can figure it out.
