@cicerone imposter,
What I described above is not voter fraud. If I live in a state where you have to be a member of the party to vote in the primary, and I go down to change my party registration from Republican to Democrat so I can vote in their primary, then after the primary-or even after the election-I go down and change it back to Republican so I can vote in the Republican primary the next year and thereafter, no law has been broken.
As for going through "all that", in my town the Town Hall has its own parking lot, and when I first moved into the town registering took five minutes from entering the parking lot to leaving the parking lot. The town next to it has a Town Hall in the center of town, but parking is not that hard to get on the streets and unless you register a day or two before the election the town election registrar doesn't have a line. Not everyone lives in an urban environment where the traffic is clogging the streets, parking is hard to find, and there are long lines in every city office.
