Player of the Week: Sen. Patty Murray (D-Wash.)

She is working on a spending bill that would avert a government shutdown, and she is simultaneously crafting a budget resolution that will be difficult to pass.

The appropriation measure is expected to clear Congress with bipartisan support before Washington runs out of appropriated money later this month.

But the budget measure is not going to be so easy.

Senate Democrats haven’t passed a budget resolution in four years, and they have enjoyed less and less the constant ribbing for it that they have received from the GOP.

Murray’s budget faces major hurdles, the first of which is the composition of her panel. Democrats only have a 12-10 majority, which means that if all Republicans vote no, Murray can afford not even one defection. That means convincing Sens.

They are not men who see the world and policy in similar ways.

Sanders, a sharp critic of any suggestion that entitlement programs be cut, last week told The Hill that the budget talks have been “very hard.”

Should Murray get her budget through committee, more stumbling blocks await on the floor.

Murray and her fellow Democratic leaders can afford only five defections. If Democrats don’t get 51 votes, senators’ pay will be suspended, as stipulated in a bill that became law last month.

But it is worth noting that Murray is on a roll. She helped expand the Democratic majority last year as head of the Democratic Senatorial Campaign Committee and later was rewarded with her Budget gavel.

Still, passing this bill might prove an even bigger challenge than tightening her party’s hold on the upper chamber.
