There is not much enthusiasim for Biden. People may vote for him just because they don't like Trump.
He's been around a long time & failed in previous presidential bids. He eventually had 8 years in the white house as VP. Was a decent VP from 2008-2016 & should have then enjoyed his retirement.
Has aged a lot over the last 4 years & seems to be a rabbitt in the headlights. Not believing he could actually end up as the most powerful man in the world, while simultaneously enjoying being in the limelight in his twilight years.
Said himself he will be a caretaker President, but caretakers step in when there is an unexpected vacancy. Caretaker football managers usually last two weeks.
Not even sure he will last 4 years, may step down after 6-18 months to give Harris a chance before the next election.
