It varies from state to state. More states are doing that.
I voted early yesterday for the first time, I usually wait until Election Day but when I drove by the polling place and saw a line going around the building, I thought jeez I can't imagine how long the line will be on Tuesday and I have a granddaughter to pick up at school.
Guys, I live in Texas, Bush country, and they said they have been getting in 1 polling place 2000 voters a day!
Oh ok. I think it's a good idea. The polls can become very frustrating on Election Day.
