Story highlights Mike Huckabee says Republicans should unite behind Trump if he's the nominee

"The establishment Republicans are all bed-wetting over this," Huckabee said on Fox News' "Fox and Friends"

(CNN) In the wake of Donald Trump's sweeping victory on Super Tuesday, former Arkansas Gov. Mike Huckabee is challenging establishment Republicans to unite behind the GOP front-runner if he becomes the nominee.

"The establishment Republicans are all bed-wetting over this," Huckabee said Wednesday on Fox News' "Fox and Friends." "Don't pretend that all of the voters who have gone out and voted for him are stupid. They are not stupid. ... They're angry, and they're angry at the very establishment who is going nuts because Donald Trump is doing so well."

The two-time GOP presidential candidate accused some Republicans of being overly dependent on Washington's wealthy donor class.
