The COVID package is being passed using 'reconciliation', which can only be used once per year, due to silly senate rules.If they can pass a $1.9 trillion COVID package, this should be a piece of cake.
We shall see soon, hopefully.
Without use of reconciliation, the Rs can filibuster anything.
Of course, its also possible the filibuster itself will go away this year.
But, Rs also like low taxes and stuff. So it is possible they may support EV credits. We'll see.
