> What about the other extreme, where every political ad contains blatant lies because anyone who doesn't do that cannot possibly get elected?

Basically an arms race of lies, where those willing to lie the most have the greatest advantage. What's worse is that the most insidious of the lies will appeal to the parts of the targets' psyches that wants very much to believe the lies, and therefore unlikely to proactively fact check (i.e Pizzagate).

And as has been the trend of late, lies that are eventually publicly debunked will be minimized as being "just jokes".
