Republican Gov. Paul LePage said during a radio interview Tuesday morning he would consider running against Janet Mills, the Democratic governor-elect, in four years if she fails to implement voter-approved Medicaid expansion in a financially “sustainable” way.

LePage said that would mean Mills would not touch the state’s budget stabilization — or rainy day — fund to pay for expansion of MaineCare, as the federal-state program is called in Maine. Expansion would provide health insurance to about 70,000 low-income Mainers.

A better way, the governor suggested, would be for Maine to increase taxes on hospitals, an idea he floated earlier this year.

“Listen, I wish her all the success in the world because if she succeeds, Maine succeeds,” LePage told WVOM hosts Ric Tyler and George Hale. “And I want her to succeed. I love this state and I want her to be very successful.”

LePage said that he and his wife, Ann, have just started discussing buying a house in Maine, where they would summer. They already own a house in Florida. No matter where he is living, LePage vowed to keep an eye on the state’s finances.

Last week, just before the Nov. 6 election, the governor told reporters in Augusta that he was planning to move to Florida for tax reasons and would teach at a university. But on Tuesday, LePage told the Bangor radio station he would live in Florida during the winter months and spend his summers in Maine.

“The only issue now is: Do we become residents of Florida or Maine?” LePage said.

It was just last month in an interview with C-SPAN’s “50 Capitals Tour” series that the 70-year-old LePage told host Peter Slen that he was done with politics and planned to spend more time with his wife and family.

The governor said it would be unwise for Mills to raid the state’s rainy day fund to finance MaineCare expansion, which he estimates would cost about $200 million to implement in the first year. According to LePage, there is about $276 million in the fund.

“If she expands Medicaid on Jan. 2, 100 percent of the cost will be borne by the state of Maine” because the federal government has not yet approved the state’s expansion application, LePage said. “If she doesn’t do it sustainably, in four years we will be where we were in 2010 and I will be back to run against her. … We’re the same age, so we could have a good time.”

The governor apparently was referring to overdue Medicaid reimbursements to Maine hospitals that confronted him after his election as governor that year.

Mills could not be reached for comment Tuesday night.

During the 14-minute interview Tuesday, LePage touched on a broad range of issues. He noted that he lost 80 pounds after undergoing bariatric surgery in the fall of 2016 and talked about his dislike of ranked-choice voting. He prefers runoff elections, which he described as the smartest, quickest and simplest way to get to 50 percent.

Lepage, who has less then two months left in office, spoke briefly about Democrats achieving a majority in the Maine House and Senate. The Democrats’ victories mark the first time in eight years that one party has gained control of the Legislature and the governorship.

When asked why Maine Republican candidates lost in the Nov. 6 election, LePage said he did not have an explanation, but he also did not accept responsibility.

“It was a ripple around the country, but I think in New England it was a wave,” LePage said, referring to Democrats taking control of the U.S. House of Representatives. “We took an old-fashioned country whopping.”

Republican Gov. Paul LePage said Tuesday he now plans to maintain his Maine residency and would consider running against Janet Mills, the Democratic governor-elect, in four years if she fails to implement voter-approved Medicaid expansion in a financially “sustainable” way.
