Andrea Singmaster is thankful for President Joe Biden. He helped secure funding to clean up a contaminated site in her Philadelphia suburb and his efforts to crack down on Medicare drug prices will help family members financially manage arthritis and Crohn's disease.
Because he’s not charismatic.
People like to point to his earlier career not aging well to current social / political norms, completely ignoring that adapting one’s values as society evolves is a desirable trait.
But really, it comes down to charisma. He’s awkward and not particularly likeable, and people will bend over backwards to justify their dislike of him despite his accomplishments.
Then there are the hardline progressives, who literally no one electable will ever please. I’m sure even Bernie would have had to make too many compromises ,or fail to deliver enough, to alienate these folks if he had taken the presidency.
