Like I said before if the mail in voting system has actual fraud or not, but as link posted proves you don't get arrested for no reason at all, and the people arresting a government official running for office, wouldn't happen if they didn't have prove, thus its up to the courts to decide his innocence not ours. But to get back to my point is that if a large number of the electorate belief that a voting system has a weakness in that it opens the door for fraud and corruption, then regardless if this is actually the case or not is not the issue, the issue is in having a system that is viewed by half of the population as fraudulent which will obviously skew any election results that might be had either way. The tried and tested system that most people the world over prefer as the most secure not perfect but most secure in person voting with ID, yields the fastest results and the most reliable results and in a contested election like this will most certainly be having doubt cast on your election process is something that can only further divide the already divided American public, thus pushing for mail in voting is not only irresponsible but also dubious as to why one would opt for a system that will yield results slowly even up to weeks after the votes has been cast, with high amount of fraud already suspected having a large delay in time will just add to the fraudulent speculation.
