In 2019, Virginia already had a Democratic governor. It was two votes away from a Democratic House of Delegates and a Democratic Senate. Virginia got those votes and more.
As a result, Virginia made it easier to vote, passing
- Same day registration, including election day
- Automatic voter registration whenever you deal with the Registry of Motor Vehicles
- No excuse absentee voting with prepaid postage on the absentee ballots
- Election day a legal holiday (replacing a holiday honoring Confederate Generals)
- Extended polling hours
- Required a paper record of all voting
- Required state preclearance of any local changes in voting
They are working on a few more
- Redistricting reform
- Joining the national popular vote agreement for electing a president
- Permitted instant run off for local elections
- Redistricting processes for Congressional districts and state legislative districts
- Reduced voter ID requirement by allowing non-photo IDs
The Democratic trifecta led to other reforms as well, but election reforms ensure the retention of all the other reforms.
