Vice President Kamala Harris is actively campaigning in battleground states, with former President Barack Obama joining her efforts in Michigan and Wisconsin, as well as other critical states like Georgia and Arizona. Polls show Harris and Republican rival Donald Trump in a tight race, with Harris slightly ahead in Pennsylvania and New Hampshire but trailing in Michigan and Wisconsin. Criticism has emerged regarding the Harris campaign's lack of a coherent closing strategy and her failure to differentiate herself from President Biden, as noted by Democratic strategist Doug Schoen. Obama, along with other notable Democrats including Michelle Obama, is expected to boost turnout among loyal Democrats, crucial for narrow victory margins. Despite challenges, Harris's campaign efforts are supported by high-profile endorsements and events, aiming to solidify the 'blue wall' in key states. Meanwhile, both Harris and Trump continue to make strategic appearances in these pivotal regions, underscoring the competitive nature of the upcoming election.
