Did he actually vote in two states?
The Republicans have tried for years to update voter rolls because there are a lot of people registered in more than one state. They move and forget that they are still registered at their old address. Updating rolls would eliminate this problem.
There are over a million dead people still registered to vote. And, yes, there are illegal aliens and non-existent people registered to vote.
We need to update voter rolls but the left fights it every time, claiming that it will disenfranchise voters. So, you want to keep this kind of problem alive.
Failing to cancel a registration at an old address is not a crime. Voting twice is a crime.
At least know the difference before you get all excited.
You must be livid at the way votes for Hillary were being counted as much as six times each this last election.
