Somehow, I'm not seeing John Brennan's endorsement of the Democrat candidate as being a big plus for O'Rourke's chances. Inmates within the confines of that giant leftist concentration camp known as Austin, Texas are going to vote for O'Rourke, anyway, and I fail to see how Brennan's well-established left-wing bona fides are going to carry much weight with normal voters.
"Beto O'Rourke! Like Gus Hall, only dreamier!"
Update: Response from Gus Hall to John Brennan -
"Hey, you ain't exactly eye candy, yourself, walrus boy!"
