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."

Adding onto Nathaniel's Google search comment ... debates can serve as a great introduction to some of the lesser-known candidates. Ramaswamy is probably tonight’s big winner in making a name for himself: 59 percent of voters had no opinion or had never heard of Ramaswamy before tonight, according to a favorability question in our pre-debate FiveThirtyEight/Washington Post/Ipsos poll. That’s likely changed after all of the talking he’s done on stage — and we’ll be tracking whether that’s a good or bad thing. Check back in at FiveThirtyEight tomorrow afternoon for our post-debate analysis.

Pence was pressed by moderators if presidents should have to pass a mental and physical test to serve, invoking President Joe Biden's age.

Pence, who is 64, initially joked that "it might be a good idea to have everybody in Washington" pass one.

He then took a serious tone, saying, "No, the American people can make those judgments."

He appeared to take a swipe at Ramaswamy, the youngest candidate on stage, stating the nation doesn't need a president who is too young either.
