Obamacare Vote to Test Democrats’ Resolve Under Republican Majority

House Republicans will hold a vote this week to change Obamacare’s definition of full-time work from 30 hours a week to the traditional 40, setting up an early test to see how many Democrats are willing to buck President Obama and his signature overhaul now that they are in the minority.

It’s part of the early agenda taking shape on Capitol Hill, where the GOP in both the House and Senate is planning votes on issues that have earned bipartisan support before, but which stalled as Democrats circled wagons to protect Mr. Obama politically.

Now, with the president a lame duck and the GOP controlling both chambers, Republicans hope for better results.

“It’s an important marker on whether both parties can work together,” said Neil Trautwein, vice president for health policy at the National Retail Federation, which supports the 40-hour proposal.
