I'm skeptical of any poll that says Trump is leading in Virginia after the GOP got their asses handed to them there in 2018, and they lost the 2019 State House elections by 9.4%. and the 2019 State Senate elections by 13.4%.
That's not accurate, you have to take into account contested seats, in the contested seats the average GOP margin in the senate was 1.5% better than Trump.
