Santorum’s not dropping out, but it looks like he won’t campaign anymore in Florida post-tomorrow’s debate:
Santorum indicates he could leave Florida before Tuesday primary

Santorum could never afford commercials in Florida, and with no free media from doing campaign events, he will be invisible Friday-Saturday-Sunday-Monday before the primary Tuesday. And this, of course, will only make more obvious to his remaining supporters his non-viability, who should then move disproportionately to Newt (the 2nd choice of most Santorum supporters.)
And it look as if Newt might need it, as the Florida polling tightens up.
There are lots of other states where Gingrich will need Santorum in the race. My vote will go to Santorum here in Michigan which is one less for Romney.
I think the Santorum supporters probably will move to Newt, regardless of who Santorum endorses (and he may not endorse anybody). He seemed to favor Romney, but on the other hand, maybe he’d prefer to fade off into the sunset and have his wife look for his income tax returns on his home computer.
