Donald Trump hits a high of 39 percent among Republican primary voters in the latest national news polls.

Trump's most recent surge in the Fox News poll solidifies his lead over a crowded GOP field that now finds Texas Senator Ted Cruz as his biggest challenger at 18 percent. Over the last month, Trump's overall support has risen by 11 points, much of the uptick coming from among men, white evangelical Christians and voters without a college degree.

Interviews were conducted since the GOP's most recent debate in Ls Vegas and after Trump came under fire by many over his controversial proposal to ban all non-U.S. Muslims from entering the country.

Trump Seen As Best To Handle Economy Among GOP Candidates

More in depth research finds much of Trump's rise in overall support comes at the expense of Florida Sen. Marco Rubio, now at 11 percent from a high of 14, and political neophyte Ben Carson, who has seen his support tumble from a high of 23 percent earlier this fall to just 9 percent in the latest poll.

Over the last month alone, support for Trump among white evangelical Christians has risen by 14 points, compared to a 12-point slip for Carson.

By huge margins, Trump is viewed as the GOP candidate best qualified to handle the economy (52) and the one who figures to be most effective against ISIS (49 percent). Cruz places a distant second on both issues at 13 and 17 percent respectively.

Trump Stumbles Against Clinton

Despite his strong showing among GOP primary voters, the bloom dramatically falls off for Trump in a projected general election against Democratic front-runner Hillary Clinton.

Just a month after trailing Trump by five points, Clinton now leads him by 11 points.

"Trump has helped himself and Democrats over the last month," Democratic pollster Chris Anderson marveled. "And while the outside probability of a Trump presidency is enough to make many Democrats root against him in the primary, they can take some solace in that Trump is clearly the least electable of the leading Republican candidates."
