The “evidence” in terms of the mass mailed ballots is simple - per Article 1 Section 4 of the US Constitution the power to determine the manner and places of elections within a State is granted exclusively to the Legislature of that State - not the Governor. The state level EO’s for mail in ballots therefore clearly violated the US Constitution.
The evidence of Deprivation of Rights comes in the form of elections officials actively blocking designated GOP poll watchers during the election and observers during the ballot counting process.
I’m wondering why you put “evidence” in scare quotes. What means are you thinking must be executed?
