The Rasmussen Poll questioned 624 likely Republican voters on December 16th and 17th (and the poll had a 4 point margin of error). Their purpose was to see if the last Republican debate had changed voter support any. Not much has changed.
Christie and Bush seem to have helped themselves slightly, but continue to poll in single-digits. Carson has slipped further, and joins the others in single digits. Trump, Cruz, and Rubio all maintain their numbers, and Trump has an 11 point lead over his nearest competitor.
