The point is the margins right now are larger for Biden than they were for Clinton in the polls. Things have 4 weeks to change. They've been very consistent this year though.
Leftists always bring up that Trump won 3 states by a small margin, but fail to mention that Hillary was only as close as she was by winning 4 states by a small margin. It's an Idiot Dem canard.
Compare that chart to 2020 where Biden has had a consistent lead, especially since June: https://www.realclearpolitics.com/epolls/2020/president/us/general_election_trump_vs_biden-6247.html Notice how much more volatile 2016 was. You saw Trump sometimes catching Clinton. Biden has held steady by a decent margin all year.
The point I'm making is that it wouldn't take much movement in the national polls to make up those gaps. PA, MI, and WI would really need to break trend to stick with Trump if Biden is +4 on election night. Especially since the Dems are more heavily investing in those states this time around.
And it wouldn't take much movement in the polls to win the 4 states that Hillary won by a total of 93k. This side is never recognized by Leftists.
In order to win nationally, Idiot Dems need to now have double digit leads in national polls in order to have a chance the way that demographics fall.
Lots of illegals vote in California. In the last midterm elections in 2018, you had young kids, probably, children of illegals lining up to register and vote on the same day in Los Angeles. Said what was happening in the country was wrong. All of them probably, got registered and voted. In Orange County where Republicans had their bastion, all 8 Republicans lost their seats. Incredible, since, they had majority Republicans in their areas. Probably, swamped by the illegals who registered and voted. One of the Republicans who was of Asian descent was even leading by a large margin the night of the election. Only to be swamped out by torrents of votes as they continued to count the votes in the days after the election.
What's interesting to me is that last time polls showed Trump and Clinton further apart in WI, MI, and PA than the national average. Clinton was winning in those 3 states by like 2 points more than she was nationally. This time around they're showing the national average doing a few points better than Trump in those 3 states. Dunno if they made changes in their methodology or what for those 3 states.
The polls are showing a bigger lead for Biden than Clinton though, not the other way around. Hence nobody thinks Biden will lose states Hillary won close races in like NH, MN, NV, and ME.
