BUTTE, Mont. — We’re stopped at our third Montana RV park and are enjoying some local TV … including some pretty nasty political ads being fired back and forth between Democratic U.S. Sen. Jon Tester and his Republican opponent, state auditor Matt Rosendale.

My wife and I have been out of Texas for about two weeks. We’ve parked our RV in West Yellowstone and Missoula, Mont. I’m wondering if we’re going to see such vitriol flying soon from the Senate campaigns of Beto O’Rourke and Ted Cruz.

The Republican is accusing Tester — a guy I’ve always considered to be a Second Amendment-loving moderate Democrat — of being a closet clone of House Majority Leader Nancy Pelosi and Sen. Bernie “Democratic Socialist” Sanders.

Rosendale has tied himself to Donald John Trump. He calls himself a “Trump conservative,” which if I lived in Montana would be enough all by itself for me to support Tester.

Most of the negativity is coming from Rosendale. Tester is saying he approves the TV ads “even if Washington doesn’t like it.”

I guess I like Tester partially because of his haircut, which is a sort of buzz-cut flat-top ‘do.

Policy-wise, he is a moderate. He supports retaining the Affordable Care Act, which hardly is a poisonous policy position by my standard.

Sure, Montana is a Trump state. The president has campaigned for Rosendale. Given the troubles that are mounting for the president, my sense is that his support for a candidate — even one here in this bastion of the Wild West — is a mixed blessing at best.

Well, it’s my hope anyway.

As for O’Rourke and Cruz … take it away, boys.
