A blast from the past: Texas Military Voting Qualifications, Proposition 2 (1954)

Members of the military - of the United States - could not vote in Texas prior to the passage of this amendment. It was ratified by a vote of 77% to 23%.

- The Texas Reference Library has detail on what else was on the ballot.

Here's the language:

For the amendment of Sections 1 and 2 of Article VI of the Constitution of Texas so as to confer the privilege to vote upon members of the regular establishment of the United States Army, Navy, Marine Corps, or Air Force, or component branches thereof, who are otherwise qualified electors; and so as to limit voting by persons in the military service of the United States to the county in which the voter resided at the time of entering such service; and for the repeal of Section 2a of Article VI of the Constitution, which now permits qualified electors in military service to vote without payment of a poll tax in time of war.

Notice that they didn't have to pay a poll tax. I wonder if this reflects changing attitudes about the United States military following WW2. The military occupation of Texas was a distant memory.
