Senate Republicans plan to use the prospect of drilling for oil in the Alaska National Wildlife Refuge to get the votes needed for major corporate tax cuts and a repeal of the individual mandate, one of the key components of the Affordable Care Act.

On Tuesday night, Senate Republicans released the latest version of their tax plan and included in it a repeal of Obamacare’s individual mandate, which is the requirement that everybody who can afford to buy health insurance must do so or pay a fine. Repealing it would result in significantly higher premiums, as some healthy people would elect to forego coverage until the moment it was needed.

Drilling in ANWR has been one of Sen. Lisa Murkowski’s longtime priorities, as it was for her father, Frank Murkowski, a giant of Alaska politics. While the elder Murkowski was never able to make the drilling dream a reality, it is now within reach.

On Wednesday, the Energy and Natural Resources Committee, which Murkowski chairs, passed a bill to allow drilling by a 13-10 vote, with Sen. Joe Manchin, D-W.Va., voting in favor, alongside every Republican.

That bill was in response to what are known as budget reconciliation instructions, a Senate maneuver that allows legislation to go through the full Senate with a bare majority and not be subject to a filibuster. That means Murkowski’s ANWR bill can now be included in the broader tax package being finalized by Senate Republicans.

Murkowski was effectively named an honorary member of “the resistance” — those opposed to President Donald Trump’s agenda — earlier this year when she twice held strong against Republican efforts to pressure her to support a repeal of the Affordable Care Act. In a conversation with outgoing office interns, she described her stand on that bill as one of the most important things she’d done as a senator.

For all senators, but particularly for those from Alaska, detached as it is from the “lower 48,” home-state priorities almost always trump national ones. Murkowski has also been one of the few Republicans to acknowledge the reality of climate change — but not so much that it would get in the way of more drilling in Alaska.
