36. Recounts in all close races is a start

Trump launched 61 court cases - some of that might turn up evidence in discovery

A Senate inquiry of some aspect(s) of the election including subpoenas (clock might run out ..).

Folks individually checking their ballot got counted and reporting if it didn't.

The Russian bomb scares - which Shapiro is looking into
The late purge of voters
FEC violations

Greg Palast concerns
