Outside of the segment on Trump's indictments and his behavior on Jan. 6, it's been a bit surprising that there's been little discussion of him otherwise. There've been a few references to actions taken prior to Biden taking office, indirectly involving Trump, but not much specifically about him. That has turned this debate into something of an alternative universe where these are the main eight candidates, not the eight who are badly trailing the main guy not in the room.

Yeah, Maya, I am surprised Trump didn’t come up more. With him not on stage, I actually thought it would be easier for the candidates to swipe at him, since there was no risk of him punching directly back. But with some notable exceptions, like Christie and Hutchinson (and even then, only on a couple occasions), the candidates showed little interest in hammering away at the primary front-runner. I think that’s a questionable strategy since none of these candidates will be able to earn majority support in the primary without stealing some of it from Trump.

Sixty-eight percent of Americans think the government is withholding information about UFOs, and three-fourths think there is some form of life on other planets. The number of Americans who suspect UFOs have been spotted has also increased, and 41 percent believe that some spotted UFOs are alien spacecraft. This has only been increased in recent years with Navy pilots reporting strange sightings over the past decade, along with recent congressional hearings about the issue.

Christie was seen smiling and shaking his head as Fox News moderator Martha MacCallum began to ask about UFO ecounters.

"I get the UFO question? Come on, man!" Christie said.

"I think it's horrible that just because I'm from New Jersey, you asked me about unidentified flying objects and martians," he continued. "We're different but we're not that different."

DeSantis revels in his record of snubbing public health recommendations to curb the spread of COVID-19. But he largely omits the closures of schools and businesses that happened under his watch.

Seven states did not issue stay-at-home orders to their residents, but not Florida.

On April 1, 2020, DeSantis issued an executive order directing all Florida residents to "limit their movements and personal interactions outside of their home." The order expired April 30, 2020, and Florida began a phased reopening in May.

Though he carved out an exception for religious services and some recreational activities, DeSantis didn't exempt in-person classroom instruction. DeSantis' Department of Education issued a March 13 recommendation that Florida schools close their facilities for an extended spring break before lengthening the closure through the end of the school year in early June.

Schools reopened in person in August 2020.
