If you look at the overall national polls, Biden is up by a large amount. If you look at the polling in the Battleground states, and even some of the usually “safe” Republican states, Biden is up.
Are the polls wonky? Have the polls been manipulated to show Biden running away with the election to discourage Republican voters?
I think one “tell” that the polls could be rigged would be if the huge Biden leads start to narrow the close the country gets to the election date. If Biden truly is leading by a significant margin, the polls will remain the same and Biden will cruise to a landslide victory. If Trump is ahead or the nation is closely split, the polls will have to narrow to within a reasonable margin of error to maintain credibility going forward.
Watch for the polls to narrow. If that doesn’t happen, Biden will probably win big. If the polls narrow, then look for a Trump win.
That’s my opinion as of today, anyway.
