“I do not think we should get into the expansion,’’ Cuccinelli said in an interview. “If I were the governor, I would not seek the expansion.’’

McDonnell told legislators last week that he was considering opting out, but he needed more information from the federal government. He said the same thing while hosting the National Governors Association this weekend in Williamsburg, where other governors expressed similar reservations.

At least six Republican governors have announced that they would not participate.

Cuccinelli’s rival for the governor’s mansion next year, Lt. Gov. Bill Bolling (R), sent McDonnell a letter last week urging him not to expand Medicaid.

Cuccinelli was the first attorney general in the nation to file a lawsuit over President Obama’s health-care overhaul. This week, he called on presumptive Democratic gubernatorial nominee Terry McAuliffe to say whether he supports Medicaid expansion.

“Virginians deserve to know if Terry McAuliffe supports this disastrous expansion of Medicaid in Virginia,’’ according to a news release. “And if McAuliffe supports the Medicaid expansion, does he plan to raise taxes to pay for it? Or does he plan to cut other state government spending?”

McAuliffe adviser Tracy Sefl said McAuliffe is not officially running for office. “Terry has not declared candidacy for office and remains focused on his job-creation and business ventures,’’ she said.

McDonnell and others hope a new Congress and president will repeal the law that they considers a massive unfunded mandate.

McDonnell, chairman of the Republican Governors Association, sent a letter on behalf of Republican governors to Obama seeking clarification on critical outstanding questions related to the federal health-care law in the wake of the Supreme Court’s decision.
