If Roberts has decided to be a traitor we have a big problem, and in that case he probably has the FISA judges on his team. If RBG goes away, Trump reelected, and the GOP wing of the Senate is not already destroyed, we have a chance to fix SCOTUS, but as long as Roberts is chief justice we may have continuing FISA problems.
Why are Republicans going against Trump? Does someone in D.C. have dirt on some of these Rinos?
