ROLL CALL: Less than 2 Weeks to Shutdown, Conservatives Cool to ‘Cromnibus.’

As House Republicans sort out how they will fund the government past Dec. 11, leadership is running into a problem: Many conservatives looking to block President Barack Obama’s immigration plan contend the House must act now rather than wait until later.

That’s a more confrontational approach than the “cromnibus” proposal floated by GOP leaders Tuesday morning. The cromnibus — a portmanteau of continuing resolution and omnibus — would incorporate 11 of the 12 appropriations bills in the House, funding operations through the end of the fiscal year in September, and couple that package with a temporary CR for Homeland Security operations, likely to extend to March.

Homeland Security houses the agencies where the bulk of the executive action implementation is expected to take place.

GOP leaders argue the cromnibus is the best way to keep the government open while ensuring a fight later on the immigration executive actions — once all of Capitol Hill is under Republican control.

They also point to a “sweetener” of sorts, a chance to vote as early as Thursday on legislation that’s been introduced by Rep. Ted Yoho, R-Fla., to “disapprove” of Obama’s immigration actions.

But it might not be enough for many of the president’s staunchest opponents in Congress.

At Tuesday’s monthly “Conversations with Conservatives” get-together, Republicans said the idea of asking members to vote for any spending bill that funds the president’s executive order — even on a short-term basis — is tough to swallow.

I can imagine.
