New National Poll Shows Marco Rubio Climbing and Jeb Bush Plummeting

The establishment frontrunner now has just 4 percent support.

— -- There's a new shift in the race to be the Republican non-outsider candidate in the 2016 presidential contest.

Ted Cruz also increased his support after lashing out at the moderators during the third debate, almost doubling his support from 7 percent to 13 percent. Voters appear to have chosen Rubio and Cruz as winners after the third debate, with roughly one-third of GOP voters who watched choosing them as victors. Four in 10 Republican voters, on the other hand, chose Bush as the worst candidate in the debate.

But the new poll, conducted from Oct. 29 to Nov. 2, shows that Carson's support may be soft. A majority of Trump supporters say they have made up their minds. This compares to almost two-thirds of Carson supporters saying they haven't locked in their votes.
