IMHO both sides are guilty of this. Clinton, Bush II, Obama, and now Trump were all constantly hit by any allegation anyone could find to throw at them, and many of them were and are over-inflated or outright bullshit.
The campaign is the same. Trump spends more time shitting on other people and trolling on Twitter than talking about what he believes or wants to do, and Biden is basically running as "a dude who is not Donald Trump." Neither candidate is particularly exciting. I'll be once again voting for the least horrible of the two.
Nobody discusses the issues, and nobody ever tries to problem solve.
Personally I think it's a form of bikeshedding. People would rather sling mud than talk issues and problem solve because all the issues we face are really hard and there are huge vested interests who like the status quo and don't want anything "fixed."
Edit: feel like people are knee jerking to this. I am not necessarily claiming there isn't corruption, just that there is not enough focus on actual ideas and too much focus on personalities.
