Steven Cheung, a Greitens adviser and former Trump administration official, told Axios opposing McConnell could become a “litmus test” for campaigns eager to show their loyalty to Trump.

Cheung said research from GOP pollster Tony Fabrizio’s team indicated that “in the primary, if you’re anti-Mitch, your numbers go up.”

“It’s a test for how Trumpian you are.”…

Tucker Carlson, one of the most influential conservatives in the country, castigated McConnell during his Fox News show last week — and promised to make the minority leader a consistent object of scorn in future segments.

“In Washington, he’s known as the nastiest old woman in town,” Carlson said on his show last week during a segment about Bob Dole’s funeral.

“This is hardly the first time McConnell has done something vicious like this, but we thought going forward we would start telling you about it, because why wouldn’t we?”
