Ben Carson not only is doing well in the polls, he's also doing well in the race for campaign cash.

FOX News Radio's Jon Decker reports:

According to his campaign, Carson raised more than $20 million in the third-quarter thanks to a rush of small-dollar donations. Right behind in the money race is former Florida Governor Jeb Bush who raised $13.4 million.

And Texas Senator Ted Cruz took in $12.2 million in the last three months.

Billionaire Donald Trump, the Republican front-runner, raised $3.9 million during the last quarter, but is not actively fundraising and is instead spending some of his own cash on the campaign trail.
