Virginia is among 18 states that have not expanded Medicaid under the Affordable Care Act. But this year, the state legislature is closer to enacting expansion than it has been in the past, and the issue will be the sticking point as the legislature goes into a special session next month to hash out its budget.

Republican Del. Barry Knight from the Virginia Beach area calls it “the 800-pound gorilla in the room.” He’s one of more than a dozen Republicans who voted to include Medicaid expansion in the House budget — along with a work requirement — this year.

It’s a big shift in the House position on the issue and comes after 15 seats flipped to Democrats in the so-called blue wave of last November’s election, which also saw the election of Democratic Gov. Ralph Northam.

“On the big-picture issues, I think it was a reawakening and a call to look at things from a different perspective,” said Republican Del. Chris Peace, from the Richmond area, who also voted in favor of expansion.
