McDonnell had said delegates should strengthen their plan. The panel made minor changes, such as uniting some split precincts.
Then members of both parties voted for the new House map. Delegate Rosalyn Dance (D) says there has been bipartisan support in the House.
"A lot of the democrats voted for it because they had had input," she says.
The governor had criticized the Senate map as too partisan since no republicans voted for it. But Sen. David Marsden (D) says the Senate did consult the GOP and election attorneys.
"The governor vetoed the bill, and we're coming back on the 25th to deal with that veto. And I think the bill that the governor will see then is going to look very much like the bill he's already vetoed," he says.
If the governor and both Houses cannot agree, a court could draw the districts, which lawmakers would use for the fall elections.
