The privilege of voting and of holding public office ought to be withheld from those who are not qualified in understanding and articulating, both in speech and in writing, the principles upon which this nation is founded.
We can't exclude some people who only vote their own interest, because in some way we all do exactly that. But, we can educate people on the universal value of voting America's interest first.
If that were the case there would be little debate in congress about the need to remove John Boehner, in my opinion.
