I for one love both Joe and HRC as inspiring figures and would have voted for them even if the other candidate was not a bigoted wannabe authoritarian.
Life in public service, continuing to keep his family together after the death of his wife, daughter, and more recently, adult son.
Also, my dad was able to get healthcare under the ACA, at a time we really needed it. I don't know how much credit for that belongs to Biden alone, but he was a part of it. He's passed away now, but I'm thankful my mom didn't have to mortgage their home at the time.
I don't think lifelong politician is bad in itself. We did try out someone without a political background, but all he managed to do was normalize racism.
My family lived about 15 minutes outside of Stillwater, OK. Thanks to DJT's rhetoric, my black in-laws only saw open racism and derogatory comments, because of both their race and religion.
I'll pick lifelong politicians over any candidate that wants to make me a third-class citizen.
I voted for Biden because although I didn't always agree with Team Obama/Biden, they weren't 10% as divisive as Donald Trump.
Anecdotes aside, I'd love to see any real data you have on this topic.
