Raúl Grijalva's campaign committee posted a new ad on YouTube today that features an illustration of Gabriela Saucedo Mercer with swirling hypnotic eyes and the Twilight Zone theme song, complete with cuckoo clock sounds.

The ad opens with: "You are entering the ultimate political universe of Tea Party favorite Gabriela Mercer -- a political universe devoid of fact or common sense."

It goes on to quote some of Mercer's political gaffes and then says you should vote for Grijalva because "he's been there for you."
