As previously noted with screenshots,the candidate ahead in RCPs aggregate polling at the end of June a year and a half before the election has won the popular vote in every election since 2008. Also,presidential national polling is by far better and more predictive than midterm or any state polling.
What advice? ,that I didn't include Gallup? Biden is net double digits upside down in that poll too,that is not good news for Biden that Im trying to hide,net double digits upside is awful .All the presidents double digits upside a year and a half before the election did not come back to net positive approval and every one of them lost re election,the last one being Trump less than 3 years ago and he had a multiple million vote advantage because of The EC and didn't have a Dr West problem. The same thing Im saying about Biden now is the same thing I said about Trump on this forum in 2019.Presidential polls and history don't have have favorites.
If elections were decided on this metric alone, we'd have a much better country. The problem is that, when you compare the disapproved to the alternative, it always ends up looking like the tallest midget.
