Turns out, Jay Leno used the term three long years ago:
LENO: In a groundbreaking move, the Associated Press -- the largest news gathering outlet in the world -- will no longer be using the term "illegal immigrant." That is out. No longer "illegal immigrant." They will now use the phrase "undocumented Democrat." That is the new term: "Undocumented Democrat.”
AUDIENCE: (wild laughter and applause)Someone who relayed Leno’s joke in 2013 — Rush Limbaugh — actually coined the term himself three years before that, in 2010.
So I’m late to the term. So where’s Trump?
