The man has gotten shockingly little credit for the advancements he's made in polling in the last two months. Nearly 10,000 people showed up to one of his events in Wisconsin and he spoke to (according to his own Facebook account) 7,500 people today in Maine. Precisely zero other candidates can brag those sorts of numbers, but people keep acting surprised that he's surging in the polls. He's 200,000 Facebook likes behind Hillary (a 100% increase since he announced his candidacy in May). How long before he overtakes her as the Democratic front-runner?
