Ben Carson is giving Donald Trump a run for his money, according to the latest Fox News national poll.

Support for Carson in the race for the Republican nomination has nearly doubled in the last two months, he is seen by voters as being more ethical than others, and he has the largest number of GOP primary voters who say they would definitely vote for him.

Running down the GOP race: Trump remains in the top spot with 24 percent, closely followed by Carson at 23 percent. Ted Cruz is third with 10 percent. Those are the only three who receive double-digit backing from Republican primary voters.

Next, it’s Marco Rubio at nine percent, Jeb Bush at eight percent, Carly Fiorina and Mike Huckabee at five percent each, and Rand Paul at three percent.

The remaining candidates garnered one percent or less.
