A group of conservatives at the National Review have just released an issue entirely devoted to denouncing the candidacy of Donald Trump.

Rich Lowry, the magazine's editor, unveiled the coordinated effort on The Kelly File last night, arguing that Trump has not supported "defining" conservative principles.

Other contributors included Glenn Beck, Dana Loesch, Katie Pavlich, Bill Kristol, Brent Bozell, and many more.

Trump responded Friday, calling the National Review a "dead paper" and claiming that its influence is at an "all-time low."

On Outnumbered today, Andrea Tantaros said she has "tremendous respect" for the National Review, but argued that they should direct their "fire" at the reason why conservative Republicans are now supporting Trump.

"The reason is that so many people feel that the establishment - the Bush big-spending, nation-building era - ran it into the ground," she explained.

She then highlighted a piece by Michael Brendan Dougherty at The Week, who wrote: 

What so frightens the conservative movement about Trump's success is that he reveals just how thin the support for their ideas really is. His campaign is a rebuke to their institutions. It says the Republican Party doesn't need all these think tanks, all this supposed policy expertise. It says look at these people calling themselves libertarians and conservatives, the ones in tassel-loafers and bow ties. Have they made you more free? Have their endless policy papers and studies and books conserved anything for you? These people are worthless. They are defunct. You don't need them, and you're better off without them.

Tantaros agreed that this was a message that Pat Buchanan failed to carry effectively in 1996, but now Trump is doing it. 

"That is the message Buchanan didn't take. Trump is taking it and that is the counter-punch to National Review," she said.
