Among the possible alternatives to Donald Trump his foes have attempted to recruit for a third party bid include a non-politician very much of the Trump mold.

According to a report in the Washington Post, members of the “Never Trump” movement reached out to Mark Cuban, an outspoken billionaire and star of the reality show “Shark Tank.” Cuban confirmed to the Post that he had been asked to run for president as a conservative option to Trump, but would not say specifically who tried to recruit him.

“I don’t see it happening,” Cuban wrote in an email to the Post. He added that those who tried to recruit him cited his “bluster and volume, combined with substance and the ability to connect with voters on a more personal basis” that made him an ideal candidate for the long-shot effort.

“He could come after me all he wanted, and he knows I would put him in his place,” Cuban said of Trump, in his email to the Post. “All that said, again, I don’t see it happening. There isn’t enough time.”

As the Post reported, a major problem for Trump oppenents trying to get behind a third party or independent presidential bid has been finding the caliber of candidate who would attract the fundraising required for the arduous task of getting on various states’ ballots.

The Post named other targets of the recruiting efforts, which so far have appeared unsuccessful. They include Ohio Gov. John Kasich (R), Sen. Ben Sasse (R-NE) and retired Marine Corps Gen. James N. Mattis.
