You know you are correct. Except for resignation, impeachment and removal and death.
Hopefully someone can tell us which three states. Arizona seems to be lurking in my mind as one of them
Wisconsin was one that I remember mentioned.
Whomever posted what I read said it was three “ swing states”.
On another forum someone said as many as 11.
I don’t know which is why I’m humbly and sincerely asking.
