Evan McMullin: Too little, too late or 2020?

It's D-Day monkeys. Not that I give a shit who you voted for. There's 2 candidates on my ballot and 3 clowns. One of the names (I'll leave the candidate/clown thing for you to decide) is Evan McMullin, a relatively no namer originally from Utah. Obviously he, nor Johnson, will admit they have as much chance of winning this thing as @DickFuld" but what is he trying to pull here? Is McMullin working to finagle Utah away from Trump or set himself up for 2020? FiveThirtyEight has been a bit wacky as of late but they did throw out an interesting scenario - should the race be deadlocked (aided by Utah going to McMullin) the House would decide amongst the electoral college vote holders who wins the presidency. The guy theoretically has a better chance in this scenario.

McMullin honestly seems like a good option for all the Republicans who won't vote Trump, hate Hilary, and just realized how much of a goober Gary J is. I'm actually surprised he hasn't gotten a lot more buzz on WSO seeing he's an ex-CIA operative that worked at Goldman with a tech VP. McMullin is the perfect candidate for all the "incoming summer analysts" to circle jerk over.

So, is he here to play some serious game or is there another angle?
