Why doesn't Trump just sign an executive order declaring the results of the last election invalid?

Answer 1

Oh, he probably already has - in bright red crayon too!  

 I swear the U.S. must have the largest number of F-ing idiots per capita of any country on Earth.  

Answer 2

States run the election not the federal govt.   He only has control of the federal govt.   States rights and all that.

Answer 3

Answer 4

He tried that and it did not work
