I don't pay much attention to general election polling this early, but I've been following the double negative or "hate both Biden and Trump" polling. Biden has the edge with those voters in the latest survey from February by Marquette.
In 2016 and 2020, the candidate that won these "hate both" voters won the election.
My bullish case for Biden is winning this group and seeing his numbers improve among Democratic leaning voters as the election nears.
A wrinkle in this is this group is affected by third party candidates naturally. So we will have to keep an eye on how ballot access fares for third party candidates this cycle. For Biden especially I am watching what No Labels does.
