Progressives need Katie Porter in Congress. (PCCC)

Elizabeth Warren says, "Katie has been my partner in these fights for years -- and she'll make a terrific partner in Congress."

This is a must-win race for taking back the House. And it's a race Katie can win.

Many experts consider this the most flippable district in the nation. Trump lost here by 5 points in 2016.

Katie Porter (CA-45) is an authentic, gut-level economic populist who will inspire voters because she is instinctively on the side of working people.

Our recent polling shows that "Warren wing" ideas such as expanding social security, reversing Trump's tax cuts for the rich, higher wages for workers, debt-free college, and allowing the government to negotiate lower drug prices are popular in this district among Democrats, Independents, and Republicans.

Katie is the lead consumer watchdog in the state of California, as appointed by Kamala Harris. She has worked with Elizabeth Warren for nearly 20 years, since she was a student in Warren's bankruptcy class.

Katie left the primary with a lot less money on hand than her Republican opponent -- who has shown that she will attack Katie every chance she gets.
