Chris Pratt seems to think that even Fox News is "far right" (which means that he probably thinks that MAGA is even more far right), although, to be fair, he also (correctly) sees CNN as far left. He believes that most people are in the middle and that people on the right and left are both "wackos".

Much like her father, Pratt's wife Katherine Schwarzenegger definitely has TDS (although to be fair, married couples don't always agree on everything).

In 2020, President Trump tweeted this message after recovering from the Coronavirus:

"I will be leaving the great Walter Reed Medical Center today at 6:30 P.M. Feeling really good! Don’t be afraid of Covid. Don’t let it dominate your life. We have developed, under the Trump Administration, some really great drugs & knowledge. I feel better than I did 20 years ago!"

Katherine Schwarzenegger's response was:

"If that tweet itself is not enough to get you fired up to want to elect Biden and get rid of Trump as president of our country, then I don’t know what is. That’s the sickest tweet I’ve ever seen. Please vote."

She followed that up with:

"I’ve also always been somebody who is super respectful of people’s choices to support whoever they want to support, especially politically. I grew up in a family with different political views, so I’m very used to that and I’m also very respectful of it. But I’m actually at a point now where if I think that I am interacting with anybody who supports a man who tweets that when there are people who have lost loved ones and who are really sick and people who are still dying because of COVID, then I just don’t really know how I can understand how you can support an individual like that. So, get thinking people."

As for Henry Cavill, he generally stays quiet about politics so far, except for the time that he took part in Blackout Tuesday.

Chris Pratt, most certainly; he's openly Christian and pro-2A. I hope Henry Cavill is, too, given his pushback against wokeness, his sincere dedication to the geeky pursuits, and his overall sense of genuine charisma.
