Fox News Poll: Trump jumps, Cruz climbs, Carson sinks in GOP race

Donald Trump, a candidate even Republicans once considered a side show, increases his lead yet again in the nomination race, according to the latest Fox News national poll.

The poll also finds Ted Cruz ticking up, Marco Rubio slipping, and Ben Carson dropping.

Trump hits a high of 39 percent among Republican primary voters, up from 28 percent a month ago. The increase comes mainly from men, white evangelical Christians, and voters without a college degree — and at the expense of Carson…

Support for Trump in the GOP race is more than double that for Cruz, who comes in second with 18 percent. That’s up four points since mid-November and nearly twice the 10 percent he had in October.

Rubio garners 11 percent, down three points from 14 percent last month.

Carson drops to 9 percent. He was at 18 percent last month and had a high of 23 percent support earlier this fall.

After that, Jeb Bush, Chris Christie, Carly Fiorina, and Rand Paul get three percent each.

Jeb Bush: ‘Donald Trump is a jerk’

Although Jeb Bush has been railing against Donald Trump all week, he still had more to say on Saturday, uttering perhaps his strongest comments yet about the Republican presidential front-runner.

“Just one other thing — I gotta get this off my chest — Donald Trump is a jerk,” Bush said to laughter and applause at his town hall Contoocook, New Hampshire.

He’s also eating your lunch, Jeb.
