it drives me fuking crazy, there's no logic involved... although have to say, I was that way about little Shrub but he didn't have two brain cells to rub together and my feelings for him came about as close as it is possible to hating a stranger who is pitifully challenged.
Politicians tend to drive me all crazy equally. Maybe because I'm always more interested in looking for the "other angle", lol. I just assume that if candidate A is driving me crazy then there's got to be some stuff about candidate B that's being overshadowed at the moment, that would drive me equally nuts.
Politicians, insurance adjusters, CRA auditors....they all circle that one level of hell.
