Four potential obstacles in House vote to end US shutdown

The U.S. House of Representatives is preparing to vote on a spending bill that has already passed the Senate, aiming to end the historic government shutdown. House Republicans hold a narrow majority and can pass the bill without Democratic support, but they can only afford to lose two votes. Key obstacles include disagreements over health insurance tax credit renewals that affect 24 million Americans, internal Democratic party tensions between progressive and moderate factions, and objections from fiscally conservative Republicans concerned about adding to the national debt.
