[WS:] So what? The purpose of Palin-like types is to appeal to a niche - a hodge podge of petite bourgeoisie, hicks, ditto- heads, militia types, insecure white males, and plain mean-spirited spiteful pricks - who need this kind of stimulation to go to the polls. Otherwise, they would either stay home or pull the lever in an unpredictable way. There might be a 38 percent minority, as the poll that you cite suggest - but it is more than enough to sway the election results.
