Obviously there are some differences between Laura Rudy and Rudy Giuliani's campaign logo (center). But when you're driving 45 mph, the sun's in your face and you're looking at a small sign surrounded by grass badly in need of mowing, blue and purple are pretty much the same thing.
Then last night, out of the corner of my eye, I spot my Rudy DVD (top) underneath my TV. That movie came out in 1993, the year Giuliani was elected Mayor of NYC. hmmmm.
