From @Maximus_4EVR Twitter post:
FYI Robert F. Kennedy Jr. is leaving the Democratic Party and mounting an Independent run for POTUS, per Mediaite and National Review.
~In a race between Trump (R), Biden (D), Kennedy (I), West (Socialist-G), and Manchin (No Labels)...
~My educated guess is West drains Progressive Radicals from Biden, which helps across the board, but especially in urban areas. In places like California and New York, it wont effect the outcome (but it will be tighter), but PA, AZ, WI, MI, and MN, it will help.
~Manchin will likely take moderate votes, more Democrats from Biden, but some Republicans from Trump. This will impact the Midwest and South. Indies will be attracted to Manchin too, which will be split in places like Florida and Ohio.
~Kennedy will take about 10-20% of Registered Democrats (Dems will spend a ton trying to discredit him in the process, and it will feel like its "Biden v Kennedy" more than "Biden v Trump" for much of the year). The real danger here is the debates.
~Dems will be opposed to the idea of Kennedy, as an Indy, being on the GE Debate Stage. My gut tells me Team Trump will push for it. However, many Republicans will caution against it. Kennedy has a misplaced popularity amongst anti-Vax M-AGA. It is likely he would win over some of the "Trump should have fired Fauci" crowd, especially the disaffected DeSantis group.
~Still, I would want Kennedy on the stage. He is essentially a good man, who is a little off his rocker at times (Mr. Green Peace and anti-2A), but I respect his love for America. I would like to see Donald and Bobby chum it up a bit. I bet they would get along. Biden will be lost on the stage.
~West will never be allowed on the stage (unless he can repeat what Perot did in 1992 and get up to 10% in the polls). But West will drain 100% votes from Biden - probably 3-5%. Manchin may be able to qualify for the debate. However, it depends on if he is George Wallace 2.0 or not.
~If I were Trump, I'd push for all four gentlemen on the stage. It will be 4 on Biden - Trump could make nice with Kennedy and Manchin, and slap West when his Socialism gets worked up, then remind the world that the chaos you see is because of 2020.
~I would say the popular vote would look like thus:
Trump 43%
Biden 32%
Kennedy 10%
Manchin 10%
West 5%
~Maybe Biden gets 37% instead, and Kennedy falls to 5ish. Maybe Manchin falls, too. It's hard to speculate where the votes will fall.
~Rigging the count in urban areas won't help much, because everyone will be voting in different directions, and the margin between Biden and Trump won't be close. Trump thrives in chaos.
Conclusion:
Biden loses the GE to Trump.
