Former Republican Sen. Bob Corker (Tenn.) on Monday appeared to voice an unwillingness to launch a 2020 primary challenge against President Trump, saying that he didn’t really see a path for a presidential candidacy.

“I think for someone to undertake that, they have to feel there’s at least somewhat of an opportunity to actually be elected,” Corker, a fierce critic of Trump’s, told reporters after a speech at the Nashville Rotary Club, according to The Times Free Press. “I see no point in just doing it to [run], you know, I just don’t.”

Corker, who served in the Senate between 2007 and 2019, added that “if I thought there was a real opportunity to focus on the kind of things that I’d like to focus on, some of which I mentioned today, I would strongly consider it.”
