Vote ASAP!
I have seen numerous cases where a dim activist simply goes into Early Voting and claims to be someone else.
They used to only do this with voters they knew to be dead, registered but never vote, etc.
Note that even if ID is required, dim election workers let the scam artist vote. In some cases, they KNOW the activist and what he is doing.
In 2012, millions of Republicans went to the polls on election day and were told that they had already voted!
What is your source for your last sentence?
