But then you've hit the nail on the head, haven't you Lars. To commit in person voter fraud on the scale you would need to sway a national election, you would literally need to build jails to hold all of these people.
You seriously contend that there are enough people out there committing a FELONY to cast one vote to effect the outcome of the election? Not to mention that it just isn't practical to organize that many people to commit a felony with little to no direct benefit, it would be the single dumbest way to try to steal an election ever.
This "problem" cited by Republicans simply makes zero sense if explored logically.
