I'm sure average 13 year old can't, and doesn't give half rat's ass about it, since average 13 year olds have different interests, but I would be glad to be proven wrong. Any proof? However, more interesting is that you think while you can disenfranchise US citizens at will, somehow you can't change eligibility age for presidency. Where this sudden reverence for tradition comes from, I wonder?
An 13 year old is in what, 8th grade? Probably the only year that most Americans ever spend learning about their own government? When else does the average american learn about their government, if not in school?
Some of Americans read those things called books. You know, on their own volition, without being forced to do it by unionized government workers. Some of them also read magazines, newspapers and such, containing plenty of information. There's also this newfasioned thing called the internets, where they say you can read about stuff too. Of course, I'm not sure how "average" your American has to be - maybe for you, average one is one that only can be taught by a teacher in a coercive mass-production setting and forgets everything he had been taught very soon. I see how you want to increase a number of such people among the electorate - if you other ideas are as harebrained as this one, you need a big supply of short-attention-spanned, never learning, reading averse, infantile electorate to gain any acceptance.
