Sooner or later you're gonna lose the droolers, and those who can't feed themselves are not a reliable voting bloc.
A further example:
Let me explain the joke: 17-year-old Trayvon Martin was pursued and killed by a guy who wasn't arrested for it, and the president said "If I had a son he'd look like Trayvon."
As all right-thinking people understand, the murder of a kid is equivalent to someone being mean to a millionaire who said a dumb thing.
Also: Rush was born in 1951 and Ann Romney was born in 1949, but drugs really age you.
