California Sen. Kamala Harris ended her bid for the presidency Tuesday, telling supporters that the campaign "simply doesn't have the financial resources we need to continue."  After a breakout performance in the first Democratic debate, her polling numbers had been moving in the wrong direction. There has also been turmoil in the campaign organization. A top aide recently resigned, saying she had never seen an organization "treat its staff so poorly."

To my supporters, it is with deep regret—but also with deep gratitude—that I am suspending my campaign today.

But I want to be clear with you: I will keep fighting every day for what this campaign has been about. Justice for the People. All the people.https://t.co/92Hk7DHHbR

Harris' recent national polling average was 3.8%, a sharp drop from the mid-teens support she was receiving in July after the first debate. This placed her fifth in the field, in a group with businessman Andrew Yang and former NYC mayor Michael Bloomberg, who just joined the race last month.  Her polling was also in the 3-4% range in the four early states, limiting her opportunity for an early breakthrough* in those critical contests. 

Despite those troubles, she was one of just seven qualifiers thus far for the final Democratic debate of the year. That debate is December 19th in Los Angeles. The six others include Joe Biden, Pete Buttigieg, Amy Klobuchar, Bernie Sanders, Tom Steyer and Elizabeth Warren. It is possible that Tulsi Gabbard and/or Andrew Yang may still make the stage; they have until December 12 to qualify.

_{*Contrast this, for example, to Mayor Pete Buttigieg, who is fourth nationally at 11%, but is leading the field with 22% in Iowa.}
