The Electors shall meet in their respective States, and vote by Ballot for two Persons, of whom one at least shall not be an Inhabitant of the same State with themselves. And they shall make a List of all the Persons voted for, and of the Number of Votes for each; which List they shall sign and certify, and transmit sealed to the Seat of the Government of the United States, directed to the President of the Senate. The President of the Senate shall, in the Presence of the Senate and House of Representatives, open all the Certificates, and the Votes shall then be counted.

 Can we find a reasonable candidate and have a grass roots write-in campaign. So far the people putting themselves forward are not it. 

 The Constitution doesn't mention a popular vote for the Executive Branch. The only votes that have ever mattered are from the Electoral College.

Write in anyone. Even if they get 100% of the popular vote, it won't matter if the Electoral College votes for someone else. 

 I’ve only seen the electors vote in line with their state. 🤷🏼‍♀️ 

 Not true. Hillary won the popular vote against Trump. It's happened several times in US history. The popular vote has always been "for show", and is meaningless in the actual process. 

 Winning the popular vote but losing the electoral college doesn’t mean the electors voted in opposition to the citizens of their state. The electoral college was put in place so large population centers wouldn’t carry more sway than states with more rural or agricultural areas. It was meant to provide equity between states. 

 Yes, and it (the Electroral College) is the only vote that counts for the Presidential election, per the Constitution.

If you can find anything about the popular vote in Article II, I'd be curious to see it.
