CHARLOTTESVILLE, Va. (CBS19 NEWS) -- The state’s elections are gaining national attention as all seats in the General Assembly are up for grabs.

Experts say Virginia could be looked at as a bellwether state, meaning the results could set the tone for political campaigns across the country leading up to the 2024 presidential election.

From local politicians, like Representative Abigail Spanberger, to national leaders, like former President Barack Obama, all eyes are on Virginia.

The Associated Press reports an unprecedented $46 million was raised by both parties in October.

J. Miles Coleman with the University of Virginia Center for Politics says a majority of the General Assembly’s 140 seats will be a close call.

"It would be very surprising to me if either chamber wasn't decided by a few seats. It's going to be very close overall," he said.

Political experts say Tuesday’s outcomes could serve as a barometer for predicting the results of the 2024 presidential elections.

New polls find former President Donald Trump slightly ahead of President Joe Biden, 51 percent to 48 percent, taking the lead in most swing states.

In Virginia, a Republican win in the state Senate and a hold on the House could pave the way for conservative policies.

"If one party is having a good night, whether that be Democrats or Republicans, a lot of the toss-up seats may end up breaking the same way, so that's a dynamic I'm watching for tomorrow night," Coleman said. "I think it would be a surprise if Republicans won both chambers of the legislature."

Polls open at 6 a.m. and close at 7 p.m. Even after polls close, voters in line by 7 p.m. can cast a ballot.
