While on the campaign trail Monday for Democrats ahead of the midterms, former Vice President Kamala Harris offered some of her harshest criticism of the Trump White House yet, calling it the “most callous and corrupt and incompetent” presidential administration in American history.Twice during her speech at an event for David Crowley, the Democratic nominee for governor in Wisconsin, Harris accused the Trump administration of wielding an agenda of “brutality” against Americans.Though in her lambasting of President Donald Trump’s character and leadership style, she didn’t mention him by name once.”We in this room, I know, understand that the measure of the strength of the leader is based on who you lift up, not who you beat down,” Harris said. “Unlike some other people who are constantly looking in the mirror, David is looking at the people. That’s the kind of leader we want.”KAMALA HARRIS CLAIMS GOP ‘CHEATING’ AHEAD OF MIDTERMS, SAYS SHE’S FOCUSED ON STOPPING THE ‘MADNESS’Her more specific, policy-based attacks came against Rep. Tom Tiffany, R-Wis., Crowley’s opponent in the gubernatorial race.Harris noted that Tiffany supported Trump’s efforts to overturn the 2020 election based on unsubstantiated claims of widespread fraud, before framing the upcoming election as a test of longstanding democratic norms.”Let’s talk about the fact that David’s opponent denied the election of 2020. By the way, we won. Yes, you can call me former madam Vice President. We won that election,” Harris said.She continued: “We are now in the phase of the moment in our democracy, while we can still hold on to it, where the people’s voice reigns, where the will of the people reigns, where the power of the people is demonstrated by what we do to organize.”MAPPED: THE STATES TRUMP AND TOP DEMOCRATS ARE TARGETING BEFORE ELECTION DAYAt an earlier event on Monday, Crowley called Harris a “huge mentor” of his, adding that his wife loves her.Tiffany pounced on the connection in a social media post, accusing Crowley of sharing Harris’ support for higher taxes, “taxpayer benefits for illegals” and “Green New Deal policies” that he argued would drive up energy costs.Over the last several weeks, Harris has barnstormed through several key presidential battlegrounds to campaign alongside Democrats, including Nevada gubernatorial candidate Aaron Ford and Senate candidates Abdul El-Sayed in Michigan and Chris Pappas in New Hampshire.Her increased involvement has only fueled speculation that she is laying the groundwork for another White House run in 2028.During a September event with NAACP leaders in Detroit, Harris said she has yet to decide whether she’ll run for president again.”I do sincerely believe ’28 won’t matter if we don’t get through ’26,” she said.
