The first anti-Obamacare bill of the new Congress, H.R. 30, the Save American Workers Act of 2015, was written to undo the part of the Patient Protection and Affordable Care Act (PPACA) that defines "full employment" as holding a job for as little as 30 hours per week.
It passed, and on the way, it became even more partisan in color than the 2014 version of the bill. In the last Congress, 18 Democrats voted with every Republican to pass the bill, but Thursday only 12 did, including all but one of the 2014 supporters (not Georgia Rep. Sanford Bishop) and two new Blue Dogs (Florida Rep. Gwen Graham and Nebraska Rep. Brad Ashford).
By turning on the bill, the Democrats made clear that they would sustain the veto already promised by President Obama, and, yes, they have the votes to do so.
If every member of the 114th House of Representatives shows up for a vote, 48 Democrats need to join every Republican to override a veto. Three times this week, when the GOP brought forward bills to approve the Keystone pipeline and delay part of the Volcker Rule, the Democrats denied them all but a handful of votes.
