It seems to me that this rash of voter fraud popping up in Pennsylvania, Colorado and Michigan are meaningful attempts to sow doubt about voting and that they are being used as a future catalyst to incite protest and ultimately unrest for MAGA to use.
Stay vigilant. Track your vote. Drop it off at a secure ballot collection site if possible. These are not mere happenings in my opinion. MAGA is not afraid to do whatever they can to get their way.
