Speculation is intensifying around Texas Democratic Rep. Jasmine Crockett, who may be preparing to launch a U.S. Senate campaign as soon as Monday. Crockett is set to make what she calls a “special announcement” in Dallas at 4:30 p.m., just 90 minutes before Texas’ deadline for candidates to officially file for the 2025 ballot.

Although Crockett declined to say what she plans to announce, she confirmed to CBS News that she has spoken directly with several Democratic candidates already in the race. According to her, she reached out last Sunday to discuss polling results she had commissioned and to address any questions they had about her potential entry.

Crockett, 44, has built a strong national profile in her short time in Congress—boosted by her frequent appearances on national TV, viral committee confrontations with Republicans, and a highly active social media presence. She has repeatedly left open the possibility of running for Senate but insisted she would only do so if internal polling showed a realistic path to victory in a November general election.

Currently, Democrats Colin Allred and James Talarico are running for the seat, aiming to challenge the winner of the heated Republican primary featuring four-term Sen. John Cornyn, Rep. Wesley Hunt, and Attorney General Ken Paxton.

A University of Houston/Texas Southern University poll conducted in late September found Crockett leading a hypothetical Democratic primary with 31%. Talarico and former Rep. Beto O’Rourke—who is not running—followed at 25% each, while Allred registered 13%.

However, the same survey showed all Democratic contenders, including Crockett, trailing Cornyn, Hunt, and Paxton in general-election matchups.

A Talarico campaign spokesperson confirmed he spoke with Crockett but said he did not receive any polling data. Allred’s campaign did not respond to inquiries.

One Texas Democratic lawmaker told CBS News that Crockett has been privately sharing internal polling showing she would enter the primary as an immediate frontrunner. “If she jumps in, she becomes the favorite with the Democratic base,” the lawmaker said, estimating the chances of her entering the race as “better than average.”

A Democratic strategist watching the race agreed that Crockett could dominate the primary but warned that a statewide victory would be extremely difficult. “If she runs, I blame Beltway consultants pushing her into something unwinnable,” the operative said. “There’s just no way she wins statewide.”
