I don't know how Biden supporters cope with the RFK Jr-included numbers in all of these polls. They always act like those numbers don't exist so that they can focus on the head-to-head.
In the RFK Jr-included poll here - even in an extremely favorable scenario where the remaining 10% breaks 80% for Biden, 10% Trump, and 10% RFK Jr, then Biden still loses by 2%
Because these are incredibly unrealistic. Even if you average all the polls, RFK splits close to 50/50 from Biden/Trump. Trump only losing 1% in a multi-way compared to Biden losing 7% is just wildly out of step.
