"Even markets can be irrational," Senator Kevin Cramer said on this episode of Plain Talk.

He was talking about activist investing which has ballooned stock prices for companies like video game retailer Game Stop and movie theater chain AMC, hitting bear investors who had placed bets on those prices declining right in the pocketbooks.

What should be done about it? Nothing, says Cramer. At least not right now. He says he's waiting to see how things play out.

Cramer also spoke about the impending impeachment trial for former President Donald Trump. The Senator has already cast a vote in favor of a motion declaring the trial unconstitutional but says he won't make up his mind on whether to vote guilty until after he sees the evidence.

Still, given his vote on the motion, it seems unlikely he'd vote for Trump to be guilty. Cramer acknowledged that while he didn't approve of Trump's actions before, during, and after the riot at the U.S. Capitol, he didn't think it rose to the level warranting conviction.

But even if Trump isn't convicted, is he someone Republicans should be following going forward?

Trump is working on remaining a relevant force in the Republican party. "He's going to be," Cramer said. "He's going to have as much influence as he wants to have."
