BATON ROUGE, La. — President Obama on Thursday praised Louisiana’s new Democratic governor, John Bel Edwards, for his decision to expand the state’s Medicaid program to provide health care coverage to thousands of residents. “He’s already delivering for the people of Louisiana,” Obama said.

Edwards’ predecessor, Republican Bobby Jindal, had refused to expand the program.

Obama’s health care law allows states to use federal money to expand Medicaid to provide coverage to more of the working poor. The federal government pays the full cost of expansion through 2016, gradually dropping to 90 percent in 2020 and afterward.

Obama praised Edwards’ move as “the right thing to do.” He said it will help the state’s finances, by reducing costs, “and it shows you why elections matter. And right now we’re hoping to encourage more states to do the right thing.”

Edwards’ office says about 300,000 Louisianans who currently lack health insurance stand to benefit from the change.

Thirty other states and the District of Columbia have accepted Washington’s offer to pay the full cost of expanding Medicaid, but more than a dozen mostly conservative states have not. It’s a situation Obama hopes to change before he leaves office next year.

In an attempt to encourage holdout states to follow Edwards’ lead, Obama will ask Congress to provide full federal funding for the first three years after states expand their programs. That means any state that expands Medicaid this year – currently the final year for full federal funding – or any year afterward would get Washington to pay 100 percent of the costs for the first three years.

The White House announced the proposal early Thursday, before Obama held a town hall meeting at a high school in a predominantly African-American neighborhood in Baton Rouge. It will be included in the 2017 federal budget proposal Obama is sending to Capitol Hill next month.

But the plan seems unlikely to gain the backing of the Republican-led Congress, which has voted numerous times to repeal the health law.

Edwards signed an executive order Tuesday calling for the state Department of Health and Hospitals to make the changes necessary to begin expanding Medicaid. He said he wants the expansion to take effect by July. It was unclear whether the state’s majority-Republican Legislature would try to block it.

Jindal had argued it was too costly for the state.
