WASHINGTON — The House straggled back to the Capitol on Monday night with just two weeks left before its likely entry into the Congressional record book for underachievement, still clinging to hopes that deals can be reached in the coming days on a budget and other once-routine bills that could ease some of the sting.

But even those accomplishments could be thwarted by a basic political calculation: Many Republicans believe they are getting such good traction from their attacks on President Obama’s stumbling health care law that they feel less compelled to produce results. Any public fight over legislative compromises could take away from the focus Republicans have kept on the health care law.

“I ran on a government that did less,” said Representative Reid Ribble, Republican of Wisconsin. “I felt the government was overreaching, and the citizens that sent me didn’t want me to be overaggressive in writing new laws. The Affordable Care Act launch is actually demonstrating the ineptitude of the federal government in handling these big programs.”

The 113th Congress has passed all of 55 laws so far this year, seven fewer at this point than the 112th Congress — the least productive Congress ever. House and Senate negotiators will meet on Wednesday to try to come to terms on a farm bill, but they remain far apart, especially on food-stamp cuts that the House is demanding. The leaders of the House and Senate budget committees will also meet this week, and they appear to be closing in on a modest deal that would set spending levels for the next two years while relieving some of the pain from the across-the-board spending cuts known as sequestration.
