Week ahead: GOP battles over ObamaCare strategy

House Republicans have planned a vote against the Affordable Care Act this week even as members of the party are continuing to clash over whether to use a government shutdown threat to defund the law.

The shutdown issue will come to a head less than a month before the new ObamaCare insurance marketplaces open in all 50 states.

As the Oct. 1 launch date draws closer, Democrats and their allies are stepping up their outreach to try and encourage enrollment in the exchanges, while Republicans are redoubling efforts to stop the law from moving forward. 

House Republicans hope to draw attention this week to one of the delays in the reform law’s implementation. The House is scheduled to vote on a bill, sponsored by Rep.

The administration announced in July that it would temporarily ease part of the verification process when people apply for tax credits to help cover the cost of their premiums. Republicans say the delay puts the government at risk of massive fraud.

House Republicans will also take aim next week at the healthcare law’s economic effects. The Energy and Commerce Committee is holding a hearing Tuesday on the law’s “challenges for states and job creators.”

Also on Tuesday, conservatives and Tea Party activists are planning a rally at the Capitol to make the case for threatening a government shutdown over ObamaCare funding. Sens.
