It is an especially tall climb for a Republican like Santorum. Democrats have a history of taking chances on unknowns and fresh faces. The current occupant of the White House was two years out of the Illinois Senate when he sized up the competition, asked himself the same question and decided he was up to it.
But the GOP has a tradition of anointing the next person in line. With more than a dozen other names being mentioned, Santorum is nowhere near the front. The last time he was on a ballot, in a 2006 bid for a third Senate term in Pennsylvania, he lost by 18 percentage points.
Yet Santorum believes that this is an altered political environment - and that this time, the process of selecting a presidential nominee could be different for Republicans.
Others agree that the old GOP script could be rewritten in 2012. "People are desperate to the point of panic in wanting to get rid of Barack Obama, and increasingly anxious about the prospects of some of our choices," said a prominent Republican strategist, who did not want to be quoted by name suggesting that anything is lacking on the GOP bench.
