I'm really against the idea of limiting voting based on IQ or school achievement.
With the latter, suppose John Doe doesn't graduate high school. However, he instead goes on to do an apprenticeship, or maybe starts his own business, or excels in some other area. Maybe he didn't graduate due to some misfortune. Should John Doe be prohibited from voting, even if he's an accomplished individual?
As for IQ, again, very wary. If someone is deemed retarded/mentally disabled/whatever, I mean, okay, sure, if John Doe can only drool and moan, then it's probably fair to say that he lacks the ability to vote, but if someone's deemed sane, then what's to stop them? There's a lot of debate as to how efficient IQ is at measuring intelligence. I'd rather sane/insane be used a benchmark, rather than some arbitrary number. Like, Fox has suggested 85. The last time I took an IQ test, I got 88. If someone arbitrarily decides that the 85 limit has to be increased to 90, then I'm out of luck.
At what point do you just kick the kids out of the house? Why can't we just have consecutive Democrat presidents?
Well, the Republicans took over from the Whigs effectively. Maybe, I dunno, the Libertarians would take over from the Republicans?
