If after the 2012 election you are told:

[Plankton5165]

A Republican wins in 2016.

I would maybe guess it's a human being born in 1982 and standing as tall as Afrojack. He'd be easily the tallest and oldest president.

It'd be sad that he'd lose in 2020.

I'd actually more likely guess that in late 2013. I don't think I even knew Afrojack was 6'10" in early 2013 so I probably wouldn't have guessed the height.
