The Voter Decides if he Id Disabled, not the Government.
In other words, anyone in Texas can Vote by Mail.
The intent here is to not allow the mailing of a ballot to every name on the voting lists. It should be obvious to everyone that the voter lists are incredibly inaccurate listing people who have moved, died, etc. A shotgun mail-out of ballots is extremely unlikely to produce a fair election.
And is it not interesting that in almost every close election the extra or suddenly found votes (usually after the polls close) are responsible for swinging the election to the left?
Mail-in ballots have a place in an election if properly acquired and used. IMHO a ballot should be requested by mail by a voter and then returned in the mail. That way there is a paper trail.
