There are a number of Democratic candidates competing for the nomination in TX-7, a district that appears to be competitive this year.
It appears that they really want a corporate drone in this race, so the that appears to be DCCC has released opposition research against one of the candidates, Laura Moser:

The campaign arm of Democrats in the U.S. House of Representatives set its sights on a surprising target Thursday: Democratic congressional hopeful Laura Moser.

The Democratic Congressional Campaign Committee posted negative research on Moser, a Houston journalist vying against six other Democrats in the March 6 primary to unseat Republican U.S. Rep. John Culberson. Democrats locally and nationally have worried that Moser is too liberal to carry a race that has emerged in recent months as one of the most competitive in the country.

The DCCC posting, which features the kind of research that is often reserved for Republicans, notes that Moser only recently moved back to her hometown of Houston and that much of her campaign fundraising money has gone to her husband’s political consulting firm. It also calls her a “Washington insider.”

………

Texas’ 7th Congressional District is new offensive territory for Democrats and an ancestral GOP stronghold. But Hillary Clinton carried the district in 2016, and a flood of Democrats soon raced to run for the seat.

Moser’s bid has been picking up momentum practically daily. Earlier on Thursday, her campaign announced it had raised nearly $150,000 in the first 45 days of the year. And in recent months she has amassed a massive online following for a first-time Congressional candidate. She is also a favorite interview subject of national publications and women’s magazines and has a passionate following among many people who supported U.S. Sen. Bernie Sanders’ presidential campaign in 2016.

This weekend, she is set to host actress and activist Alyssa Milano in the Houston-area district to help get out the vote during early voting.

Seriously, you have a candidate who is raising money and creating enthusiasm, but you are going to push an anti-union lawyer (Emily’s list) and a former Goldman Sachs executive (DCCC) because they are releasing f%$#ing opposition research in the f%$#ing primary. (Link)

Seriously, the party apparatus is hopeless.
