Carson

 A coupla months ago Bill Maher joked that Ben Carson was polling so well so that he could "win Thanksgiving", ie your racist uncle at Thanksgiving dinner could claim he couldn't be a racist because he was a big fan of Carson, putting you hippie liberals in their place; as soon as Thanksgiving was over they'd immediately ditch him as their favorite candidate. I laughed at this line, thought it was clever but didn't really take it seriously, but now looking at the sudden timing & trajectory of Carson's free-fall from leading the polls it doesn't seem so funny anymore.
