Outside of polls taken by media we have actual regional and national registration numbers. We also have actual voting starting with interviews of people who have already voted.
Annnnd, again, we have a lot of that stuff that's favoring Harris and the Democrats.
I'm not sure where you are getting your figures. If you have something from an actual impartial source that shows Trump winning a landslide, please share it, because I'm not aware of it.
I am aware that surveys by Ipsos, Reuters and others showing Democrats are more enthusiastic about voting for their candidate. I've seen numbers that correlate with huge Democratic registration numbers among young voters who are likely to vote for Harris. Harris has a huge lead in fundraising. In Pennsylvania, Democrats figure they need a gap of at least 400,000 returned early ballots to feel they'll win and are aiming for 500,000 and I think as of last night with eight more days for early voting they are three-quarters of the way to the 500,000.
Yeah, Harris apparently isn't doing as well with certain minority demographics as Biden did, but she's also gained about 4% on Trump with non-college white men, who are a much larger voting block that several of those smaller groups combined.
Even if you are right and Trump's doing well, there's no clear evidence that he's forged some kind of commanding advantage.
