Democratic strategist James Carville has publicly criticized Senator John Fetterman for allegedly undermining Pennsylvania Governor Josh Shapiro's bid to be Vice President Kamala Harris's running mate. Carville accused Fetterman of being a 'great backstabber' in modern Democratic politics and warned that he would need to address this behavior post-election. Fetterman has denied directing concerns about Shapiro to Harris’s team and pushed back against Carville's assertions, previously telling him to 'shut the fuck up.' Tensions have escalated as Fetterman reportedly campaigned against Shapiro, who was viewed as a strong candidate for Harris's position. Ultimately, Harris selected Minnesota Governor Tim Walz instead. This conflict highlights a rift within the Democratic Party as it approaches the upcoming election season.
