You are still reading? Okay, well that was unexpected. Most people go with the option above.
So, to start off, mail-in ballots. Okay, that is a legitimate concern. After all, someone can just pose as a mailman or mail woman, intercept the votes, change the votes, and send them to where they need to go with their opinions on it, thus rigging the election. So, considering this risk, what might you propose?
An online survey, perhaps. Seems flawless, right? Wrong. For starters, the website might not be secure, thus letting hackers in so THEY can change the votes, thus rigging the election. Also, you have to find a completely unbiased person like a judge to head the website and work it, and this could be hard to find.
Well, what about a vote that is dropped into a box, handled by government officials? By now, both parties, Democrats and Republicans, have realized that government officials are biased. Now, they do not agree on which exact officials are biased, but they agree that most are biased towards their particular party. Further, what about curving the spread of COVID-19? You need to consider that, even with precautionary measures, the virus could still spread. Also, the service could be slow with the measures in place, thus making it less of an incentive to even cast your ballots.
So what is the best solution to this problem? Well, in my opinion, it still should be mail-in ballots, but in a different way. Instead of sending a vote for Donald Trump to the same address, have a mailing address that is only Republicans. Same for Democrats. This makes sure that there is a higher chance of no one changing the ballots, because it is the person that they want anyway.
Now, you might be thinking, besides "THIS PERSON IS A DEMORAT WHO CAN SUCK JOE BIDEN'S BALLS", that a person could change the number of votes by adding more. This can be taken care of by having an inspector of the opposite party go over and count the number of ballots on the spot.
