Republican lawmakers, right-wing media outlets and influencers, and Trump himself are pushing conspiracies about Biden’s health and the debate in general.
The first massive favor I'll do is give you the benefit of the doubt and accept you're saying this in good faith and not as a right-wing sock puppet.
The next massive favor I'll do is accept your (ostensible) plan is wildly successful, far beyond what you could reasonably hope for. Everybody is so moved by your comment that you convince 80% of Democrat voters to vote independent and every single one votes for the same independent party. Hell, I'll even throw in 10% of Republican voters.
The only thing we won't give you is the ranked choice voting needed to stop your idea being dumb as fuck. We'll stick to reality for that one.
So tell us how the next 4 years play out in your head. Polls close, votes are counted. Democrats 9.8%, Toothfairy Party 44.1%, Republicans 45.9%.
Aww, don't start being coy, tell us what happens next. Explain how our problems are solved after following your advice. I've given you the best possible setup I could, assuming a level of success unquestionably beyond what you're able to achieve.
Unless you're willing to give us even a token explanation of the second half of your plan, it really does look like "Republicans win the election" is where your plan ends.
