If it did I want to know what the hell was going on in the heads of voters who said “This dude is such a sleazebag, he told a woman that she was historically sexy, so I guess I’ll vote for Donald Trump.”
I don't think the scandal caused anyone to switch from Democrat to Republican. Truly swing voters who can swing either way don't really exist anymore.
But its possible it caused 70k potential Democratic voters to stay home.
I know it sounds weird, but sometimes a senator gets more votes than the presidential ticket and helps the presidential ticket. Its a reverse cottail effect. The only reason Hillary won New Hampshire in 2016 was because Maggie Hassan won her senate race. Its possible Biden only won Arizona because of Mark Kelly who over performed him.
Remember, Cunningham was running ahead of Biden most of the race
