Former President Barack Obama will hold a rally on Saturday in Southern California on Saturday that will feature seven Democrats running in key U.S. House districts currently represented by Republicans.

The Los Angeles Times reports:

In his first major foray on the campaign trail ahead of November’s midterm election, former President Obama will drop into Southern California on Saturday, holding a rally to boost seven Democratic candidates running in competitive House districts across the state. His appearance, one of just a few overtly political events he’s held since leaving the White House, is a sign of the high stakes in this year’s election as Democrats try to wrest back control of the House. It’s also an indication of California’s considerable role in Democrats’ hoped-for path to victory, with all seven Democrats competing in Republican-held districts that supported Hillary Clinton in 2016. Democrats need to capture 23 seats to take back the House. Details of the time and location of the rally have not yet been released. … [T]his weekend’s rally will mark his first stump speech this election season. A spokeswoman for Obama said Saturday’s event was just the beginning of a “focused, strategic” lineup of fall campaign appearances.

Democrats have been targeting the seven districts because they are places where Hillary Clinton earned more votes than Trump in the 2016 presidential election.

However, as Breitbart News noted in July, Republicans still have a good chance of defending these seats. In the June 5 primary, total Republican votes outnumbered total Democrat votes in six out of the seven districts.

And in the seventh district, Republican Diane Harkey led her opponent, Mike Levin, in a recent poll. Levin is one of the few Democrats running in competitive districts who has embraced House Minority Leader Nancy Pelosi (D-CA).

Pelosi hopes to return as Speaker of the House if Democrats win a majority in November.
