Battle of the Boys and Election 2016
Clock Boy: Not Trump
While he hasn't explicitly endorsed any candidate, his comments and those of his dad make it clear that Trump is a no-go for multiple reasons. And they've been hanging out with Democrats in DC recently so expect a Hillary endorsement at some point.
Balloon Boy: Trump
B-Boy has always been a bit of a wildcard so it shouldn't be surprising that he'd go for the wildcard candidate. And by wildcard I really mean attention whore.
Bat Boy: ?? Trump?
Sadly Bat Boy hasn't been active politically since 2008 when he endorsed McCain then switched over to Obama. His whereabouts and current activities are unknown but assuming that he's even aware of the election in his cave hideout, I have a feeling that he'd go for Trump. Just a hunch on my part though.
And then there's the real bellwether of the election: space alien.
Space alien: Probably Hillary
Space alien is bit hard to peg and he hasn't been active in politics in recent years either but his endorsement/prediction record going back to Reagan in 1980 has been 100%. He supported Clinton both times, then GW Bush, and then Obama. He hasn't said anything to date but based on his long personal history with the Clintons I'm guessing he's on Team Hillary.
