Polls are rigged to manipulate the masses...but no one is falling for it anymore. The poll bandwagon effect is dead. Nobody with a ounce of common sense believes for a second that Biden can beat Trump. That leaves two alternatives. The pollees are lying or the pollers are. My money is on the pollers.
Polls certainly
can be rigged if that's the objective, but any
legitimate poll publishes its methodology, which exposes that. So when you see a poll question going "would you be less likely to vote for John McCain if you knew he had fathered an illegitimate black child?", you know that particular poll is bullshit. That's why you vet the poll just like you'd vet a headline, to make sure the content supports the claim.
Pollees lying, on the other hand, is impossible. That would require said pollees to be organized, and to KNOW IN ADVANCE that they were going to be polled, and to mutually agree on what they would say. No legitimate poll could get there because they use random samples. This is the stuff of tinfoil fantasies.
Speaking of said fantasies and the wishful thinking of the "nobody with an ounce of sense" malarkey, Rump has consistently, more consistently than any POTUS in polling memory, flown well below the 50% mark in approval throughout his entire tenure. He's over 50% DISapproval right now, which is where he's been since inauguration, even with a national crisis going on. That's not exactly an indicator of invincibility, just the opposite. Couple that with the fact that he also was unable to pull that 50% mark in the infamous trio of Michigan/Wisconsin/Pennsylvania -- all three of them -- and that indicator gets softer than an ice cream cone your kid left on the dashboard on a sunny day. Even Utah .... Rump could not pull 50% in frickin' Utah, with an R after his name. Rumpbots have reason to be concerned. Bigly reason.
