This not only reveals how weak this voting block is, it also shows how ignorant most of the voters in regards to the facts or details about the candidates, truly is.
You are absolutely correct about Santorum, but you get viciously attacked for rightfully pointing it out, complete with history and documentation to back up your information about him. I can say that I have fully investigated Santorum and find the same alarming things from his past, but I have also been attacked for pointing his many contradictions, out to the forum.
This blind, impulsive stampede and Lemming mentality will only prove to ruin us later. It always does.
What you point out is a startling difference between the average Newt supporter and the average Santorum supporter. The average Newt supporter readily admits the problems and simply says that the ability to attack liberals and the history of success in the 90's is more important than the mistakes - which we readily admit.
Contrast that with the average Santorum supporter, who instead of admitting that Santorum screwed the pooch with Specter - they attack Toomey. Instead of admitting Rick is a pro life big government big union guy - they go back to something tired like Pelosi on the couch (as if we don't know that).
What it tells me is that the Santorum campaign - positioned as wind driven snow pure - will crumble under the first few consecutive days of attack.
