"Late Show" host Stephen Colbert last night touched upon the GOP's last-minute scramble to nominate anyone but Donald Trump.
The Republican establishment is "in a deep, deep panic," Colbert said, because, "they don't want to be with this guy, but the voters are choosing this."
"It's like an arranged marriage," he continued. "And unlike Trump's other marriages, this one could last eight years."
In desperation mode, the establishment "tried a new approach of a very old approach" by dusting off Mitt Romney, who spent a good portion of a speech yesterday morning telling voters every reason not to vote for Trump.
"They broke the seal on Mitt's hyperbaric dignity chamber," Colbert said. "And he shambled out and brought the pain."
On Romney's claims that Trump is not a "business genius" -- evidenced by Trump Steaks, Airline, Vodka, et al. -- Colbert said, "True, Trump has put his name on some terrible investments. For example, four years ago he endorsed Mitt Romney for president."
