Kentucky- Maybe it’s time to rent “Predator” again. The 1987 sci-fi horror movie has spawned a trio of unlikely politicians: Arnold Schwarzenegger, Jesse Ventura. . . and now Sonny Landham, who is running for the Senate in Kentucky.

“They always said there was something in the water down in Mexico,” where the movie was filmed, Landham told us. “I guess it turned out to be a political bug.”

The 67-year-old, who had tough-guy roles in ’80s flicks like “48 Hours” and “Action Jackson,” may be best known for (spoiler alert!) his memorably grisly death at the hands of an extraterrestrial hunter in “Predator.” On Wednesday, Landham announced he’s running against Senate Minority Leader Mitch McConnell (R) on the Libertarian ticket — and his phone hasn’t stopped ringing. He expected local coverage but was “overwhelmed by the international response” — including from casting agents who’ve suddenly remembered his name. “I said, ‘Wait a minute, folks. I’m going to win this race. This is mine to lose.’ ”

Libertarians think that presidential candidate Bob Barr has a shot in Kentucky and that Landham can beef up that ticket. He got permission from fifth wife Jessica to enter the race; he’s banking that his modest lifestyle (Screen Actors Guild pension and Social Security, less than $30,000 a year) makes him an average-Joe alternative to McConnell and Democrat Bruce Lunsford.

Landham is confident he’ll get the 5,000 signatures he needs to get on the ballot. “I know there are a lot of things that make me a colorful person,” he said, adding he’s got nothing to hide — not even his early career in adult films. “That was 30 years ago,” he said with a laugh. “If you’ve seen the porno movies, you’ve seen my shortcomings.”
