Republicans in swing districts across the United States have defied their party leadership and joined forces with Democrats to push for legislation aimed at extending the expired Obamacare subsidy program for three years. This move signals that the Republican majority in the House of Representatives faces political risks in the upcoming midterm elections.On Wednesday, nine Republican House members sided with Democrats in a procedural vote, a move that starkly reflects lawmakers’ concerns over the sharp rise in out-of-pocket premiums for Obamacare enrollees.This procedural vote paves the way for a full House floor vote later this week on a standalone proposal to extend the subsidies for three years. However, the extension is unlikely to become law. Senate Republican Leader Thune has stated that the House bill would die in the Senate, and Donald Trump has repeatedly opposed a direct extension.
