RICHMOND, Va. -

With less than two weeks left in the General Assembly session, it appears that state lawmakers are headed for another stand-off over the state budget.

Lawmakers have found common ground on other high profile issues, including improvements to the mental health system and tougher ethics rules.

But Medicaid expansion is a different story, and it has become the major flashpoint of the General Assembly session.

Another day brought another demonstration in Capitol Square. Supporters of Medicaid expansion said the state is losing $5 million a day in federal aid, by refusing to extend health insurance benefits to more low -income Virginians.

"25 state have signed up, because they realize the can't afford not to, and Virginia's in the same situation," said Senator Henry Marsh (D-Richmond). "So this is critical. This is a moment in history where we can make a difference."

House Republicans fear a major expansion of Medicaid will be a costly mistake for the state. A budget standoff they say would threaten basic services.

"I hope what they're not going to do is say we're not going to do anything until you sell Medicaid expansion," said Delegate Kirk Cox (R-Colonial Heights), "and then we know frankly that's nothing more than improper leverage. "

With the House and Senate so far apart, a public that's split, and few other issues that could foster some give and take, Roanoke College Professor and WDBJ7 Senior Political Analyst Harry Wilson says it's hard to see how they will work this one out.

"There's no horse trading to be done, because there's no other horses in the stable," Wilson told us. "This is the only horse, so there's nothing else running out there to trade with. So again I think it becomes even more difficult to find a way out."

Wilson says he's not taking any bets on it, but he won't be surprised if the General Assembly session goes into overtime.
