They will need to adjust if they want to win elections anywhere outside urban populations.
You need to remember that Biden had to actually run against the far left to win the nomination - remember in the debate when he said he had. "Beaten the socialists" (Bernie)?
You see it everywhere. Dems are struggling to build winning tickets because their primaries nominate the "wokest" candidate, then cant compete in the general elections.
Ive seen some rural areas that Dems would lose historically by about 30%, but they are now losing by 70% - 80%.
Maher is totally correct
