Harris and Minnesota Democratic Governor Tim Walz — whom the vice president announced as her running mate on Tuesday – have been barnstorming across the Midwest since Walz joined the ticket. Harris spoke to a crowd of thousands at a basketball arena in Philadelphia, Pennsylvania and even posted a side-by-side comparison of crowd sizes on her campaign's Truth Social (which Trump owns) account on Tuesday night. The top photo of Harris' rally shows the stadium packed to the rafters, while the photo of Trump's crowd size shows the attendees are mostly concentrated in the lower bowl.

"Same arena in Philly," the @KamalaHQ account wrote.

Meanwhile, Sen. JD Vance (R-Ohio) has been struggling to muster the same enthusiasm during his campaign stops in comparison to the Democratic ticket. On Wednesday, a video of a Vance rally in Macomb County, Michigan — which Trump comfortably won in both 2016 and 2020 — showed there were approximately just as many journalists present as there were supporters. This prompted some to ridicule the GOP vice presidential nominee as "low energy."

Aside from his Thursday press conference at his Mar-a-Lago estate in Florida, Trump has done only eight public events since the late June debate with President Joe Biden. Harris and Walz, in the meantime, have a packed schedule after announcing a seven-state blitz of rallies across the country, including in states deemed safe Republican, like Montana.

Both Harris and Walz have also been outpacing the Republican ticket in fundraising. Last month alone, the Harris campaign announced it brought in $310 million in donations — the bulk of which came in the last week of the month after Biden announced he was exiting the race and endorsing the vice president. Trump and Vance raised $139 million, which NPR noted came in a month in which the former president was officially nominated at the Republican National Convention and survived an assassination attempt.

After announcing Walz, the vice president has raised roughly $41 million more this week, with the Democratic National Convention in Chicago still to come later this month. Quartz noted that throughout Walz's six terms in Congress, he raised a total of $11.3 million over that 12-year period.
