*** Santorum’s last chance (really, this is it): With Mitt Romney holding a sizable delegate lead and with more prominent Republicans (George H.W. Bush and Marco Rubio) formally endorsing the former Massachusetts governor, Tuesday’s GOP primary in Wisconsin is shaping up to be Rick Santorum’s last chance -- in math and perception.
If Romney wins Wisconsin, Santorum can’t stop him from getting to the magic number of 1,114 delegates, according to our math. When we crunched the numbers showing that Romney would fall about 50 delegates short of the magic number, that ASSUMED Santorum would win Wisconsin, as well as pick up more delegates than he did in Louisiana. When it comes to perception, Wisconsin is Santorum’s final opportunity to convince Republicans that this race isn’t over, and a win in the Badger State would do the trick. Can Santorum pull off a win on Tuesday? Well, we’ll have a new NBC/Marist poll on the race tomorrow morning that could answer that question.
