So far, the closest thing a Republican here has said as a justification to Trump trying to disrupt the election is that Americans are no pro-social enough to be trusted with universal sufferage and therefore we need a benevolent dictator. I guess there is the half-argument that what has worked in the past will continue to work regardless of change in circumstances. That's the default Republican argument in general.
Did you not read my post and just skipped over to latch on to Jessica's post instead?
I guess that's the other argument. That accidents happen. They will always find a way to happen. For example, in 2004, I got a notice in the mail (the first election I voted in) after the election that my ballot wasn't counted and I had to re-register to vote. Good thing I was living in a safe state where I was pleasantly surprised when Bush carried the county at only 42-54 and that the House candidate got within 10 points of winning.
