It's becoming clear that most Republicans, if not all eventually, are planning on ostracizing Trump over this issue. Rather than focus on election integrity, they will attempt to make the case Trump's actions in response were the more egregious issue. Set your calendar for Mike Pence being the star witness of the prosecution, in one form or another.
Then that would tell me that these certifications are done under duress, which would make them all illegitimate.
Who’s running against Rubio in the primary (on August 22)?
They can if they choose to resign BEFORE the Electoral Certificates are presented to the VP. What happens AFTER that resignation can be debated, but- there would be no Constitutional VALIDATION of the President Elect, until a VP was seated in accordance with the U S Constitution. THIS is what Pence SHOULD have done, and he would have been in compliance with the Constitution.
Pence had THIS move to counter any fraud that he suspected had taken place and EVERYONE knows there was MASSIVE fraud.
