doesn’t matter.
Connecting the Freedom Caucus to the RATs is a loser.
Threatening to primary them buys nobody nothing on our side.
The RATs don’t need to be energized.
The entire GOP, Freedom Caucus included, are energizing the Democrats by basically working to make sure each and every one of Trump's policies fail simply because they want Trump to fail. They're already threatening border wall funding and Gorsuch. Do you think the Freedom Caucus is going to actually fight for the border wall, or are they going to make some noises about it and then support Paul Ryan, McCain, et al., insuring the wall never gets funded? They will keep at it for every one of his policies, and it really doesn't matter what you say or think about it. It's just a fact that these people are NeverTrumpers.
The only thing to do now is to fight them hard, or embarrass them into submission, rule by executive authority, and prepare to primary as many of them as possible.
