Rep. Sheila Jackson Lee ran an ad Saturday for her Houston mayoral campaign that displayed the wrong date for election day.

The television ad showed a message at the end directing the audience to “vote on or before December 7.” Voting day for the Houston mayoral race is December 9. Early voting ended on December 5.

Jackson Lee (D-TX) is in a runoff election for Houston mayor against Sen. John Whitmire (D–Houston). She trailed Whitmire in the November election by 7% — 43% to 36% — but neither candidate got to the required majority vote needed to win.

A November poll from SurveyUSA and the University of Houston after the election showed Whitemire holding his lead against Jackson Lee at 42% to 35%, with 22% undecided.

Jackson Lee’s campaign ad focuses her policy message on gun control, abortion access, small businesses, increased funding for police, and increased funding for schools.

Jackson Lee played defense on the campaign trail after an October leaked audio that exposed her calling a staffer a “fat-a** stupid idiot” and referring to other staffers as “f**k-ups.”

“Nobody knows a Goddamn thing in my office – nothing,” she can be heard saying in the audio, reported The Texas Tribune.

The congresswoman blamed the leak on a “Whitmire operative” and expressed regret.

“I want to convey to the people of Houston that I strongly believe that everyone deserves to be treated with dignity and respect, and that includes my own staff,” she said per The Texas Tribune. “I know that I am not perfect. I recognize that in my zeal to do everything possible to deliver for my constituents, I have in the past fallen short of my own standards and there is no excuse for that.”
