It’s more like Blue-collar and anti-snob revenge.
Santorum's dad was Blue-collar; about the only way I see Santorum being able to claim "blue collar" status is that he's been so sympathic to labor unions, voting AGAINST right to work laws. Santorum was a lawyer, has (I believe) an MBA and a law degree, and has spent most of his life as a Senator, and I think also as a lobbyist. He is certainly a "snob" in some ways -- he lectures the rest of us about morality and one gets the sense that he looks down on repentent sinners such as Newt because he believe himself morally superior. He is arrogant, and arrogance is a form of snobbery.
I'd rather have Newt, who has demonstrated true humility, doesn't presume to lecture ME and MINE about "values" and morality, and doesn't pretend to be something he's not.
Godspeed Newt Gingrich.
