Daily Kos commissioned a poll in VA. Here are the results:

Today, Daily Kos announced key findings from a statewide survey of Virginians commissioned through Civiqs. The poll of 868 registered voters was conducted online from Feb. 5-8 and reveals a strong preference that Gov. Ralph Northam resign (60 percent)—including among Democrats (58 percent) and independents (52 percent). An even stronger 64 percent of black voters think Northam should resign, and 56 percent of respondents who voted for him in 2017 now say he needs to go. Additionally, even in light of the controversies surrounding the Democratic governor, lieutenant governor, and attorney general, Virginians still favor Democratic candidates (46 percent) to Republicans (38 percent) in this fall’s legislative elections.

868 give a MOE of +-10, IIRC, but that’ still pretty close for him.
