Vice President Kamala Harris is coming back to Philadelphia this week in an appearance that would mark her 11th visit to Pennsylvania since she became the Democratic presidential nominee, and 17th this year.

And that’s part of what is powering what people familiar with Obama’s plans told CNN will be the most active closing weeks of an election the former president’s had since his own last campaign. More rallies are coming every week.

Former President Barack Obama will be in Las Vegas on Oct. 19 to rally voters to vote for the Harris/Walz ticket and other Democrats on the ballot, ahead of the upcoming early voting period.
