This lends support to one of my wacko ideas: That only the fathers in intact, two-parent famiies (with children) should be allowed to vote. Result: No Jimmy Carter, no Clinton, no Soetoro. And probably no Bushes, no Dole, and no McCain.
That is an interesting idea, with absolutely no chance of being realized. Perhaps in a related vein, I've considered the following as a definition of an adult. An adult is financially independent (e.g. a taxpayer), successfully married, raising (or having raised) at least one child. Men and women both meet the definition. Only adults would have the franchise.
A possible additional criterion for voting would be to not be a government employee, or receive primary funding from government contracts. Members of the military would be excluded from this additional criterion. By the way, this would give a boost to the school voucher idea, and could change education, and the character of future generations.
