Yeah, they did that here in 2014 with peer pressure and the likes. The most ridiculous thing that occurred was "The Vow" which appeared two days before the referendum in the shittiest of shitty tabloid newspapers, promising the people of Scotland new powers, more say and the political equivalent of a goody bag. It was so cartoonish I didn't think people would fall for it, but some did, and it was enough to swing the vote. Needless to say "The Vow" never came into effect. Surprise! Surprise!
Kamala's not promising anything, let alone horeshit, so my prediction is sadly a Trump win.
I think you're being a bit over dramatic. The US is already fucked. It's Rome before the fall. If Trump gets in the inevitable decline will only happen quicker. The Democrats are wolves in sheep's clothing who merely slow this decline. A two party system controlled by the same lobbyists is only an illusion of democracy. Until the American people break out of that, there's no hope. I don't hold out much hope for America. The collapse has been on the cards for decades. A country gets the president it deserves. The US is built on greed, corruption, decadence, fraud and imperialist ideology. Everyone else in the world can see it for exactly what it is. Goodbye America. The experiment failed.
