@NovaHunter is right, he really can't.
He can direct state law enforcement, he can Veto, and as the de facto leader of the Republican party in Virginia he can help to set the legislative agenda. But he can't just unilaterally repeal law. No matter how much we may want that to be true.
Our new Republican Attorney General might be able to do something, with the Governor's backing, if for instance there's a case to be made to the State Supreme Court that some of those bad laws violate Virginia's Constitution.
Either way, we can help Youngkin in a couple of ways.
The first is to continue to put pressure on the Democrats in the Senate who are from conservative districts. These are the same Senators who helped us kill the AWB Bill last year, mostly out of fear of losing their seats if they voted for it.
The second is to be ready to give our new Governor a majority in the Senate in the 2023 state wide elections (and keep the House!) so that he can really get some things done during his last two years.
There's still a lot of fighting to do, and we need to remember that it's really up to all of us to get it done.
