Sen. Mike Enzi (R-WY) is using his Budget Committee power to direct other committees to come up with some kind of Obamacare replacement plan, because his budget
will repeal it, and do it through budget reconciliation.
There are no specifics—yet. The budget resolution calls for repealing Obamacare and instructs two committees of jurisdiction, the Finance Committee and the Committee on Health, Education, Labor and Pensions, to report out an alternative by July 31, 2015. The plan calls for using "reconciliation"—a rule that allows the Senate to bypass a filibuster on fiscal items if both chambers agree on a budget resolution—to adopt a replacement health care plan. […]
[T]he budget steers clear of politically perilous proposals and sticks to ideas that are easy for Republicans to defend: a 2.4 percent annual hike in military spending starting in fiscal 2017, cuts to non-defense domestic spending and "waste," greater state control of Medicaid, and no new taxes. It lacks specifics about how it would meet its lofty goal of a $3 billion surplus by 2025.
So, this is less the Republican Senate governing than the Republican Senate undoing government. What the proposed budget won't definitely have is
"too many words" about how Republicans want to turn Medicare into a voucher program. It also does not include the controversial rule House Republicans have
created to prevent a transfer of funds into the Social Security Disability program to preserve it at current levels.
Even using budget reconciliation (the filibuster-proof method that may or may not be kosher with Senate rules) there's some big hurdles for Senate Republicans: A bunch of senators in purple states running for re-election. Also, too, House Republicans.
