Hill Republicans said coordinating with Mr. Romney, who is the party’s presumptive presidential nominee, boosts the chances that the two sides can avoid clashing over one of the big issues of the fall campaign but it ups the chances that the House GOP will miss its self-imposed June deadline for rolling out its alternative to Mr. Obama’s blueprint.

“From the policy perspective, we can do all these great things, but if [Mr. Romney‘s] not on the same page with us, then that’s a recipe for political disaster,” Rep. Phil Gingrey, Georgia Republican and a medical doctor who sponsored the medical-malpractice reform the House passed in March, told The Washington Times. “So, clearly, there has to be some coordination on all of that.”…

Rep. Tom Price, a Georgia Republican who has put forward one of the most comprehensive GOP plans, said the challenge is to agree on how broad the reform should be. He was more optimistic that they might roll something out by June.

“What are we at — May 9, 10?” he said. “We’re in great shape.”
