You may not like Santorum and have a preference for another candidate, but Santorum was the last person with a chance in 2012. Going by the rino logic then he is next in line.
Then Huckabee who was the “last person with a chance” in 2008 would have been next in line for 2012.
This “next in line” stuff is not as real as some pretend, that is why the veep from 2008 was never the next in line.
Santorum was driven from office in a history making loss, worse than the famous Christine O’Donnell loss, coming out ahead in the musical chairs “anybody but Romney” primary of 2012 doesn’t elevate him into presidential levels.
