Santorum will endorse Romney. Meantime, instead of putting his supporters to work for Newt, he is going to try and build some kind of conservative movement, so he can keep his hands clean.
The only missing part - and this should be interesting to watch - is how well and how long he withstands Romney's and the GOP's commands to endorse... he wants to put it off as long as possible, but he obviously is not a man of any kind of strength... And they will make him promises, and then threats...

Based on 473 Republicans, Error +/- 5.
“Please tell me which candidate you would be most likely to support for the Republican nomination for President. Former Speaker of the House Newt Gingrich, Texas Congressman Ron Paul, or former Massachusetts Governor Mitt Romney (RANDOM ORDER)”
