Yes, that's the plan.  In the House, there are 48 members of the Freedom Caucus, aka the Liberty Caucus, down two since Mike Pompeo is now director of the CIA and Mike Mulvaney is now Director of Management and Budget in the Trump Administration.  That's enough to block "Progressive" legislation and hold the Republican Party's feet to the fire.  Since 2010, the GOP has been running on a complete repeal of Obamacare and passed 7 bills to do just that (when they knew it wouldn't become law).  Now that they have the opportunity to do it, they're getting weak-kneed.  If we can block what amounts to watered-down Obamacare, it will die on it's own.  Insurors are dropping out right and left and premiums are soaring.  The Freedom Caucus calls itself "The Conscience of the Republican Party," which has always stood on a platform of less government, lower taxes, less regulation, and more economic freedom.  The Freedom Caucus actually means it.  No bill is better than a bad bill.
