Texas is (has) recognized the following 13 as eligible as write-in candidates for president on the November 8th General Election ballot:
@Texas Yellow RoseSome years ago, when I was involved in Texas elections, I was on the Resolution Committee on election night in our county, did that 10 plus years. In those days, the counting machine in Central Counting on election night, would kick out any ballot that had a write-in on it. That ballot came to the Resolution Committee to be counted. Mickey Mouse always got the most write-in votes and we had to count those, plus Daffy Duck or any other write-in candidate.
On election night in Central Counting, there was a designated time the person running central counting, had to call the Secretary of State with the number of votes for all candidates and she had to include the write-in votes for Mickey Mouse and the others. After that call, there was another designated time to call in again with updated votes.
Finally, Texas wrote a law dealing with write-in candidates. By a certain date in late summer, all write-in candidates had to sign up with with the Secretary of State and only those write-in candidates were legal. We didn't have to count Mickey Mouse and others after that law came into effect.
So, if your county uses paper ballots and you write-in Mickey Mouse or his friends, that vote won't be counted.
