Exactly how can it do that? The members of the Freedom Caucus are outnumbered 10-1 by the other members of the House. If the rest of the Republicans truly are no different from Democrats, there isn't a damn thing the FC can do to even slow down their legislation either in committee or on the floor. They wouldn't have anything close to the number of votes.
The only way the FC will be relevant on legislation is if the rest of the GOP isn't just the same as the Democrats. But that goes against everything you guys apparently believe.
Poison pills by amendment for one, 12 appropriations bills instead of one do-or-die omnibus bill, full use of parliamentary procedures if fast tracking is gone... among other things. I don't know yet as I have not seen the final rules.
And you're right. By and large, if the RINOS stick together, especially with the crats, there ain't a lot that can be done... But there's way more now than they were going to get, and you will surely see it put to work.
