WATCH: Former Presidents Obama and Clinton Campaign For Kamala In Swing States

Former Presidents Barack Obama and Bill Clinton will be out on the campaign trail in swing states to stump for Vice President Kamala Harris as the Democrats ride a surge of popularity less than four weeks from Election Day.

While Vice President Harris campaigns in Arizona and Nevada ahead of her Univision Town Hall Thursday night, President Obama will headline a rally at the University of Pittsburgh, where he'll be joined by Pennsylvania Gov. Josh Shapiro, to kick off a 27-day road trip aimed at bringing in younger voters. 

Obama is focused on voters who can put the White House, the House of Representatives, and the Senate in Democratic hands, an aide told Reuters. The former president has already helped raise $80 million for the Harris/Walz 2024 presidential campaign, and his popularity is expected to bring in more donations and voters over the next few weeks.

President Bill Clinton will make stops in Georgia on Sunday and Monday before traveling to Helene-battered North Carolina for a bus tour later in the week to reach rural voters.

Both former Presidents appeared at the Democratic National Convention in Chicago in August to support Vice President Harris' official nomination for President.

New polls indicate that Vice President Harris is pulling far ahead of Donald Trump with suburban voters and other key demographics. Trump hasn't led a major poll in over two weeks as his campaign flounders financially, while the Harris/Walz campaign continues to garner endorsements and record-shattering donations pushing them past the $1b mark.
