Who is Rick Santorum? Candidate Looks Beyond Iowa After Strong Finish

Former Pennsylvania Senator Rick Santorum may have lost by eight votes to Mitt Romney last night, but was the clear winner of Iowa's first-in-the-nation caucus.

For Santorum, who has been toiling in the second or even third tier for months and months, to come to life and finish second, barely, is frankly astonishing.

It also means name recognition for the relative unknown, much of it positive (although some funny things come up if you Google Rick Santorum), and money.

How - and whether - he keeps it up will be a key to his success or failure going forward, and the honeymoon ends quickly with New Hampshire looming Tuesday.

In his quasi-victory speech last night, though, he was nothing if not optimistic, summing up his attitude in two words as the GOP campaign continues: Game on.
