"Idiots and lunatics"

I was reading through the Texas Constitution tonight and ran across a part that has since been superceded by the U.S. Constitution. The particular section states:

ARTICLE VI.

Suffrage.

Section 1. The following classes of persons shall not be allowed to vote in this State, to wit:

First -- Persons under twenty-one years of age.

Second -- Idiots and lunatics.

XDDDDDD

I'm not entirely sure how they expected to enforce that, but okay historic fellow Texan buddies! *giggles some more*
