Santorum and his vests

Julia Felsenthal examines the Rick Santorum's penchant for sweater vests:

So what is Rick Santorum trying to broadcast about himself with his sweater vest? Which sweater vest paradigm does he fit into? It’s not totally clear. Writers have speculated that Santorum’s vest may represent an attempt to align himself with the common man. When Santorum wears vests embroidered with his campaign slogan, or other emblems—which makes him look like a guy wearing the schlubby swag from his office’s annual picnic—I can almost buy it. But when he wears unembellished vests—which he buys from Jos. A Banks, and occasionally Brooks Brothers—the look is more WASP than everyman. When he talks about his choice of clothing, Santorum—who gives the impression he doesn’t know whether this sweater-vest thing is going to backfire or make his campaign—doesn’t seem to have the firmest hold on what he’s doing.
