I urge American voters from coast to coast to vote for McMullin/Finn in states where they are on the ballot and to vote for them as a write-in in states where they are not on the ballot.
McMullin and Finn will restore honesty and integrity to the American political system.
If people want what you want, they'll have to vote Republican, and hope for a Faithless Elector scenario.
A vote for McMullin outside of UT is a vote for Hillary.
On the other hand, if trends continue the way they are going, it is possible that neither Trump nor Clinton would have 270 EV, which creates scenarios that are interesting.
I have little doubt that House Republicans would love to elect a President other than Donald Trump. They are in a conundrum because folks will have actually voted for Trump, and that counts for something, but both they, and a lot of Republicans, would take any off ramp they could find to substitute someone other than Trump, and they would be doing so almost 2 years before they face the voters again.
I believe that the key to this happening is for McMullin to instruct his electors to vote for some other Republican for President that the House will support, and for Mike Pence for VP. That begs a question of who that Republican would be.
Ted Cruz?
Marco Rubio?
John Kasich?
Jeb Bush?
Lindsey Graham?
Mitt Romney?
Paul Ryan?
I don't see McMullin as having the background to actually be chosen as the next President. He's impressive for a Senate candidate, but he has no political base other than Utah, and in some other Mormon communities; beyond that, he's no more viable a candidate than you or I would be, resume and all. (Although I think he's got more on the ball than a number of folks who DID run.) I think that if McMullin blocks the path to 270 for both Trump and Hillary and chooses wisely, he could be the most stupendous Kingmaker in American History, and POSSIBLY be the next VICE-President or Secretary of State.
