Yeah, this could get really bad. I mean, I can imagine a candidate whose American citizenship is dubious, being sponsored and funded with money laundered from, for example, George Soros and the Saudis ... a communist, crypto-Muslim, anti-American mole in the White House, doing the bidding of our enemies.
Don't laugh! It could happen.
I think you forgot to add at the end of your post: “Oh wait ...” ;-)
You think it hasn’t happened already...It has.
