No. The only way to secure the right to vote is if the right to vote is entirely unconditional. You state it in as plain as terms as possible: the government WILL NOT prevent anyone from voting who has reached the age of 18.

The right to vote DOES require citizenship. It also precludes residency in to states (you can only vote in one of them legally).

It also can be removed if you have been sentenced to a felony.

The right to vote is definitely conditional and we are well within established criteria to determine those conditions.

Yes, but age and citizenship are easily met and entirely objective standards. A four year old doesn't have the intellectual capacity to understand the issues, and I recognize that there must be a proper age standard someplace.

While your reply to this may be that, of course, there are some mentally retarded people out there that meet the age and citizenship requirements that have the intellectual capacity of the average four-year old, my response to this is that:
a) the number of these people are so small in number simply to not make any statistical difference. Moreover, the percentage of these people that are both registered to vote and who actually vote is, no doubt, nearly zero.
b) Moreover, an IQ test is again a basically subjective examination. I'd rather run the risk that a few nitwits are voting than to allow the government to condition the right to vote on subjective means.

I recognize that voting rights can be stripped by a felony conviction. I feel this is unconstitutional and the government shouldn't have the power to do so.
