Biden will win the popular vote by a record-breaking amount, 100%; there is no question about that. However, the United States does not elect a president in accordance with the popular vote.
Biden can lose the electoral college at the fringe, which is literally every other metric. If you care about the presidency, care about the fringe; and do everything possible to shore it up.
Edit: The Republican House could bring immediate legitimate and bipartisan articles of impeachment against Biden for 1) sidestepping Congress to arm Israel and 2) abuse of power to foment genocide.
The Pest is the shit. True story.
