Honestly this makes me more favorable towards Clinton's campaign.
Seems like harmless messaging. Fires up the few who are big into alien conspiracies+ willing to vote for a Democrat, and I can't imagine it
loses anyone's vote.
Of course, I'm of the view that Area 51 is just a diversion. In the hypothetical scenario where the government did have communication with extraterrestrials I highly doubt it would be in a place that's become such a part of pop culture. Same for the other theory that it's where the military tests all its top secret tech. I imagine the base is actually rather mundane.
