I'd support Vance, though I am starting to doubt his #populist credentials after his fundraising tweet that basically went like this
"Pay $10,000 to dine with myself and Peter Thiel"
Mandel trolled him with a post like this:
"Pay $10 to eat french fries with me at midnight in a Denny's parking lot"
I'd still vote for Vance though, because he isn't a lunatic. Up until recently, I thought Mandel was a neocon in Trumpist clothing. However after he said that George Soros and the Deep State caused COVID-19, BLM, ANTIFA, and the Capital Riots, I realized he is ing insane. I wasn't really following the election when he made the poll about "which type of illegal causes more crime". I'm guessing that was your evidence for your claim that he is racist. Timken is an out-of-touch elitist. The other candidates aren't really serious.
Mandel is whatever you want him to be. He's not insane, he's a grifter trying to get your attention by saying inflammatory stuff. His policy views are pretty much limited to attacking Democrats and ordering Denny's at 1am. Vance isn't perfect but he's the best option available. Timken is better than your description, but she's also not going to win. Bernie Moreno is also interesting, but also not going to win.
That sounds reductionist.
