NEWYou can now listen to Fox News articles!

The reaction among GOP candidates to Tuesday night's Democratic presidential debate in Las Vegas was one of universal disdain for either the candidates or their platforms.

Frontrunner Donald Trump live-Tweeted the entire debate, but was far from his usual bombastic self. However, the businessman did question the credentials of the lower-polling candidates.

Trump also said that former Maryland Gov. Martin O'Malley "has very little chance" and retweeted a Twitter user who asked "Why is [former Virginia Sen. Jim] Webb there??"

Trump's final verdict:

Former Florida Gov. Jeb Bush joked with reporters at a town hall in New Hampshire Tuesday that he thought playoff baseball would make for better viewing than the debate.

"Dodgers-Mets, or [Vermont Sen.] Bernie [Sanders]?" Bush said. "I don't know."

In the event, Bush did tune in for the debate and focused his ire on Hillary Clinton.

Former Arkansas Gov. Mike Huckabee sparked an outcry with this Tweet, which some declared to be racist.

Undeterred by the criticism, Huckabee doubled down, including a link to the tweet with this message castigating his critics.

At least one candidate couldn't make it to the end of the night. South Carolina Sen. Lindsey Graham decided he'd had enough of what was being said onstage.
