This framing of a battle between fresh progressive ideas for the future versus stale reactionary Trumpism could prove effective in solidifying base Democratic voters for Biden. Those critics are correct that President Biden needs to go beyond the progressive Democratic base and pick up a healthy share of up-for-grabs voters to repeat his 2020 victory. The larger problem is the unstated assumption centrist critics share with progressive advocates: the singular key to a Biden victory is nailing down a series of policy positions in an ideological sweet spot on the political spectrum.
