My bet is that Santorum will be endorsing Cruz once it is clear he is the conservative choice. I respect Rick Santorum. He was our district’s congressman before he was elected to the U.S. Senate.
I think Santorum’s running again. He probably sees himself as next in line since he narrowly lost to Romney in the primary and then Romney lost the general. Sort of like Reagan and Ford in ‘76. Plus Santorum has already poo-pooed the shutdown and taken a subtle jab at Cruz.
