I wish we had younger leadership, but it is what it is. Biden is completely correct here, and I honestly don’t doubt that he wouldn’t be running otherwise. Who the hell would want to spend their last years in an incredibly stressful and highly visible position where half the country wants to hate you – when instead you could be retired and do book deals and the like? If not for Trump, I would oppose Biden just on the basis that the best thing for his health is to not be president.

Trump is an existential threat. Biden has beaten Trump before. Biden has an incumbency advantage. Biden is an accepted consensus/compromise by the party. He’s the safest candidate for beating Trump. It may be possible that there’s a better candidate who could also beat Trump, possibly by higher margins even, but we don’t have the luxury to test that.
