I like Santorum ok, but I’ve forgotten or didn’t notice what you are referencing. That in itself is an issue.
Santorum is the ONLY candidate who will not put off the female voters (a crucial demographic that shows Newt losing in spades) and his blue-collar appeal will peel of blue states into the Republican column. He wins PA and with Rubio as his VP, FL falls into the red column and its all over for Obama. This is about winning the general and is much more than derailing Romney. While Newt dishes out red meat, he is undisciplined and unelectable and un-telegenic and Obama will scald him over his prior support of mandatory health insurance purchase.
