Democrats are lazy people, and lazy voters; having to get up and vote in person is too much for them. And Democrat politicians know it.
The mail voting is there because they are used to having everything mailed / shipped to them without them having to get up and doing things.
I saw someone jogging alone outside in the Florida sunshine with no one close by in an n95 mask. Retarded. I guess we know who they voted for and can identify them.
