I strongly urge either early voting or mailing in your absentee ballot.  This is because they are expecting a huge turn out: about 40,000 voters compared with the prior record of 25,000 voters in the 2018 Dem. primary.  Combine a large turnout with a reduced number of polling places and confusion because people can’t find their newly assigned polling places…   You see what I mean.

Addendum:

I VOTED!  Sunday morning at 11 AM, June 14th. No lines. I was the only voter at the election site in East Hampton (Windmill Village). Over 1.5 days only 42 people had voted early at this site.  Everyone wore masks and gloves and observed 6′ distancing, and it felt safer than going to the grocery store.
