Well, to be fair, he should have stepped down a year ago, or at least 3 months ago. I vaguely remember him saying he was going to be a 1 term candidate in 2020.
Anyway, I respect Biden. I honestly think he was a better president than Obama, Bush, Trump and Clinton. Perhaps the best since Carter or JFK.
That would be more in line with the actual American tradition.
But personally, I would recommend to only allow filibusters in the House, which has a more proportional representation, and to not allow it in the Senate, which has the least proportional representation, even less than the electoral college.
