You can be like Trump and deny the results of the election or you can roll with the punches and keep fighting.
Of course Biden will be seated. He was chosen in a most illiberal way but chosen none the less. I don't see the point in denying that. Now were on to who's interest he's going to serve. His cabinet is speaking volumes now.
I don't recall anyone yelling for a dixiecrat from Delaware in the primary (cept maybe Rick) and after a party insiders decision to collapse the field of candidates to Biden (not even third IIRC at the time, a historic first we never talk about) to the preferred party chosen candidate is a poor example of the will of voters being freely exercised in the selection process.
To be honest, I don't know if Rick is pulling my leg with Yellen's progressive bona fides. I was just curious to know where the progressive chorus of 'Yellen for Treasury' was coming from. Fox business reporting has the inside track on progressive politics apparently...
