I have a hard time trusting that my cable bill will get to Comcast on time via the USPS. I've seen unopened UPS and FedEx envelopes left in the street, out in the rain. Voting by mail gives me personally no more faith that my vote will be counted correctly than does a digital voting machine. Voting in person and on paper gives me some level of comfort, but I'm always cynically curious what happens after I leave my polling place.
