Symptoms include raving politcal swings (almost exclusively to the far-right), inappropriate sexual outbursts, uncontrollable urges, vastly improved vocabulary (which they are ever too willing share), near limitless (but unfounded) belief in their political ability and progression into a (self-confessed) economic superior.
