West Virginia, unlike Virginia's Democrat-led government, is now controlled by Republicans in the House, the Senate and the governor's mansion.
GOP House member Gary Howell, chairman of the Committee on Government Organization, told Fox News that 43 out of 100 West Virginia House members are sponsoring a resolution that would let West Virginia accept some of the largely rural Virginia counties unhappy with how things are being run in Richmond.
"It probably originally started as a way just to give them moral support, but it has been snowballing and we have been receiving all kinds of information from people and a lot of questions asking, 'How do we do this?' 'What do we need to do?'" Howell said. "It's turned fairly serious that some of these counties actually wanna leave, join the state of West Virginia, and we'd like to welcome them in."
More than 100 cities and counties in Virginia have declared themselves Second Amendment sanctuary jurisdictions, meaning their local police would not enforce new statewide gun control laws.
"The parts of Virginia that are more like West Virginia and much less like the I-95 corridor and the tidewater region, they're the ones that are reaching out to us," Howell said. "As you get closer to the urban areas, they more attuned with big government, a little less freedom, and we don't see those coming over."
Howell says anywhere between 30 and 46 counties could potentially take up West Virginia – which split from Virginia around the time of the Civil War due to disagreements over slavery – on the offer.
While land has changed hands between states many times through U.S. history, it is exceedingly rare that it happens on the scale Howell is proposing and often only after arbitration or a ruling from the Supreme Court.
"We see our brothers really under attack, our way of life. What we have here in West Virginia we treasure, and parts of Virginia treasure that way of life," Howell said of the areas that could join the state.
The text of the resolution requires any Virginia jurisdictions wanting to join West Virginia to have their citizens vote on the proposal before Aug. 1. West Virginia voters would then have the option to accept those areas in a statewide referendum during the general election in November.
Howell said taxes and pro-life legislation could also be reasons why rural areas in Virginia would want to join his state.
"Give them the opportunity to go someplace where they can be governed the way they want to be," he said. "This may be a trend in the future to help prevent strife in our country."
