Late Friday, an unknown challenger emerged against Lubbock Mayor Dan Pope for the upcoming municipal election.

Self-described Texas Tech student John Cothran filed to run against the incumbent Pope for mayor. The filing was accepted by the city on Thursday, but not announced until Friday afternoon.

According to Cothran's Facebook profile he is from Carrollton, Texas and came to Lubbock to attend Texas Tech University.

During the past month, some of Cothran's most-recent public Facebook posts have been concerning gun control. Here's a screenshot of the posts, edited for profanity (direct link to post #1, post #2, and post #3):

Meanwhile, it's unknown if Cothran has previously run for office and/or served as an elected official.

The municipal election is scheduled for Saturday, May  5, 2018.
