It turns out that Donald Trump's campaign is no joke, and after the Republican front-runner's big win in the Nevada primary this week, the warnings from those who believe the controversial businessman would be a dangerous president are starting to get serious.

There was even an air of caution in comedian Stephen Colbert's humorous monologue about the Republican primary on CBS' "The Late Show with Stephen Colbert" Wednesday night. The host gave his thoughts on the race now that, post-Nevada, it appears that Trump's nomination seems near inevitable.

"I’m not sure if I’m horrified or entertained," Colbert admitted. “It’s like one of those nature documentaries where the python unhinges his jaw and slowly swallows the capybara ... and then becomes president of the United States.”

Colbert also joked that the billionaire candidate is frustrating, well, other billionaires who have poured massive amounts of money into the election in the form of campaign donations and super PACs.

“This billionaire having his way with our election is shocking and unthinkable to the billionaires who [usually] have their way with our elections,” Colbert said.

The comedian went on to say that even though Florida Sen. Marco Rubio, the apparent consensus establishment favorite in the field, might not have initially been the most inspiring candidate to Republican voters, they may need to rally behind him if they hope to prevent a Trump nomination.

"Republicans aren’t just relying on money; they’re also relying on Marco Rubio, a man who doesn’t mind telling you he was not your first choice,” Colbert said. “He’s just saying the election’s not getting any younger and America needs to settle. He might not be the president of your dreams, but you’ll learn to love him.”

Colbert is far from the only person now urging Americans to get serious about Donald Trump. Many pundits in the media are now eating crow over their erroneous prognostications that Trump was not a viable candidate in the race and on Wednesday, liberal journalist Matt Taibbi penned a searing essay for "Rolling Stone" chronicling Trump's surprising stranglehold over the 2016 election and the present difficulty facing any alternative candidates hoping to stop him.

As it stands after the Nevada primary, Trump has a large lead in the delegate count, with 79. Texas Sen. Ted Cruz is in a distance second with 16 delegates, and Marco Rubio has 15 delegates. 1,237 delegates are needed to secure the nomination.
