I can't say I have a lot of sympathy on general principles after the standards applied to Conservatives in the past election, but even if I did, I'd have to say that since he occasionally refers to his blindness in off-handed ways himself in public speaking, it is pretty much a legitimate part of any stage impression of him.
If he calls attention to his own condition, he's ripe for the picking.
Governor, when you elect to be a politician you've got to expect to be ridiculed--whether in pure harmless jest or deliberately by those who might not like your policies. You live in a fishbowl. Your every action is scrutinized, analyzed, commented on. You can forget about having a life, because you've just given it to your constituency.
Stop whining and get real.
Governor, if you can't stand the heat, get the hell out of the kitchen.
