Well, the question wasn't directed to me, but I'll weigh in: people who don't pay income tax shouldn't have a say in how my tax money is spent, nor should they have a voice in choosing those who make the decisions. Too many of these believe they have a right to the fruits of my labor - and vote accordingly.
I agree on this. The founding fathers decided on voting standards for a reason. Those who participated, invested, contributed, and had a stake in the nations welfare got to vote, and only they got to vote.
Now, I am not advocating the standard they used. Woman, all races, land ownership or otherwise, etc. Morality has evolved and so has society.
My basic standard is that of a productive member of society, the specifics of which can be debated all year long. But I think some basics are employed, student, retired, not unemployed for more then a certain period. If your spouse works and you stay at home as a homemaker, that's fine. In short, you need to be a productive member of society and not a leach. Those on welfare or living on government handouts should not be able to vote on a bigger handout at the expense of the productive members of society.
You should also need a basic understanding of the structure of our government and how it works. If you can't give me a basic explanation of the make up of congress, you shouldn't get to vote. If you can't name the branches of government and give a basic explanation of their roles, you shouldn't get to vote. I don't see how someone who doesn't have a basic understanding of a system can ever hope to make an informed decision on who to vote into that system.
