I largely agree with what you're saying.
Honestly, though, this is nearly all blatant political obstruction from the Republicans. Biden calling republicans' bluff with the border/aid bill is proof-positive of this. And it's so absurd and even self-defeating for Republicans that after having listened to Maddow's Ultra podcast on the proven nazi infilitration of Congress during the 1930s, I thoroughly believe Russia has a stranglehold on the Republican party right now.
