Republicans in Congress are getting ready to answer an election-year question that has dogged the party’s campaign for months: How would it replace President Barack Obama’s healthcare law if the measure is overturned or repealed?

House Republicans are working to create a legislative blueprint they can sell to voters after the Supreme Court rules on Obama’s Patient Protection and Affordable Care Act, the nation’s most sweeping healthcare legislation since Medicare and Medicaid in the 1960s.

Lawmakers and their aides say a Republican plan would focus on controlling healthcare costs and allowing people to retain coverage while changing jobs. They will avoid Obama’s comprehensive approach to extend coverage to 32 million uninsured Americans.
