U.S. Sen. Ted Cruz’s re-election campaign is trying to paint challenger Beto O’Rourke as a potty-mouthed punk who drops f-bombs at random.

Social media response has been, well, a bit different from what the Cruz campaign expected. The revelation seems to be making the Democratic challenger seem more cool.

This mini-tempest makes me laugh and it reminds me of something that happened back in my hometown of Portland, Ore., during a race for the mayor’s office.

Incumbent Mayor Frank Ivancie’s 1984 re-election campaign dug up a 1978 picture of a challenger, Bud Clark — owner of the legendary downtown Park Blocks watering hole the Goose Hollow Inn — “exposing himself” before a statue. The picture showed Clark with his back to the camera pulling open a trench coat with the caption “Expose Yourself to Art.”

Ivancie, a man with no discernible sense of humor, thought the picture would doom Clark’s insurgent candidacy. It did precisely the opposite. It called attention to the challenger and — no pun intended — exposed Ivancie to be a stuffed-shirt prude.

Clark won the election, defeating Ivancie.

So, with that I want to hail the attempt by Sen. Cruz’s team to make Beto O’Rourke out to be a young man with a foul mouth. It well might produce the same result that occurred in Portland so many years ago.
