Unlike other anti-Trump groups, the Lincoln Project has weighed in to Senate races and has begun endorsing Senate candidates. It has backed the Montana governor, Steve Bullock, in his Senate bid against the sitting Republican Steve Daines.

Then there’s Republican Voters Against Trump, a group led by Bill Kristol, a well-known neoconservative and former chief of staff to then vice-president Dan Quayle, and Republican consultants Sarah Longwell and Tim Miller.

That group is focused on organizing anti-Trump Republicans.

“Lincoln is doing two things really well. One is narrative-setting, and just beating Trump over the head with hard-hitting attacks,” Miller said. “And they’re also working on Senate races, which we’re not doing. I think that, frankly, they’re bringing the sledgehammer and working on Senate races, and we are elevating these peer voices in a way to persuade voters.”
