Yes, both of our choices are too old. But, Biden is a far better choice than Trump. I myself, have been critical of Biden's age. He was not my first choice back in 2020. But, I'll take Biden over Trump any day. I'll take what we have right now over what we had from 2016-2020. None of Biden's policies are worse than Trump's.
Furthermore, I will take the party that stands with the LBTGQ community, that stands with women, that stands with keeping rights rather than removing them. Is Biden and the democratic party perfect, hell no. They also pander to corporations, though not quite as much. I know going in all promises won't be kept, but I also know I'm not getting chaos. I'm not getting a party that sent it's base to attack the Capitol. I'm not getting a party that puts a man over the country. I'm not getting a candidate who's base includes neo nazis (yes, some of them, not all of them are). Im not getting a candidate who fills his cabinet with family members and is corrupt as shit, while platforming the opposite. I'm not getting a candidate who has been indicted for treason and who wants to use the station of office for his own personal gain, to order his trials stopped, and to take revenge on those he considers his enemies. I don't understand how anyone with a moral compass votes for that guy.
