They could extend SCOTUS to another 2 members. I don't believe Biden will.
The key point is that regardless of what Biden says he is a conservative practising Catholic.
Both parties will play real politik IMHO. Jarvanka will have Trump keeping this issue alive until after 3 November IMHO so as to distract public discussion away from Trump's coronavirus non-performance. Biden will play real-politik on this with a goal of seeing Trump somewhat hoisted on his own petard BUT within a more important strategy of quickly moving discussion back to Trump's coronavirus performance and the knobbling of the post office.
