I live and voted on the South Shore today, and it was the most people voting I have seen at my voting place.- tom
Across the border in CT I voted around 4:20. The people standing outside holding signs consisted of 75-80% GOP signs. Their were a few Dem sign holders, but most Dem signs were on the ground with no one holding them.
After I voted (a 3-5 minute wait for a booth) I asked the sign holders about turnout. They said it was steady all day and the parking lot (about 50 legal spaces) was almost always constantly full from 8 AM on. I ended up parking on the lawn. During lunch they had two cops directing traffic as the lot was full and traffic was backed up onto the main road.
I’m also on the South Shore and voted at 9AM. It was pretty light but I just drove past the high school and there is a line of cars going in and out.
