Biden much more a Rockefeller Republican than an FDR Democrat.
Biden is very much status quo, or at least returning us to the centrist status quo of the Obama years. I wished Obama was going to be an FDR/Reagan realignment figure, though he talked a much more moderate game, and never tried. Actually I wanted Hilary in 2008 to hit the ground running, save the economy, and then Obama to be her successor. At that time, he'd be more experienced and could maybe be a transformational figure.
Not long after W Bush's infamous presidency, the GOP started taking over statehouses and Congress under Obama's watch.
The Dems have allowed unions to get crushed and Big Business to triumph, and that's a large reason they are shaky. Yeah, Biden is trying to win with the FDR coalition minus the formerly Democratic solid south. The industrial Midwest, which the Dems helped sell out to globalization is the key battleground.
