Unlike Obama, Biden did not campaign on hope and change, he campaigned on opposing the socialist inclinations of Sanders progressives and an aggressive foreign policy of planetary domination. He assured rich donors that nothing will fundamentally change under his presidency and his transition team is full of corporate sociopaths, war pigs and propagandists. Biden has been a corporatist warmongering authoritarian throughout his entire career, and as his mental capacity continues to deteriorate he will function as nothing more than an empty vessel for his establishment handlers to advance their most pernicious agendas through. The empire has not gotten less desperate since Obama was in office, it has gotten more desperate.
If I prove right about this, the Biden administration will generate backlash just like that which arose in response to the Obama administration, and that backlash will be more severe than its previous iteration. This is absolutely guaranteed. You can only oppress, neglect and enrage a population so much before the discontent begins to grow.
There is absolutely nothing American leftists can do to prevent this backlash from coming. They will have absolutely no say in this administration’s policies or behavior; BidenCorp has no reason to listen to them, has made no pretense of having any interest in listening to them, and is even freezing Sanders and Warren out of cabinet roles already.
All US leftists will have any control over is whether this backlash will break to the left, or if it will break to the far right.
