Harris, the first Black woman and Asian-American on a major US presidential ticket, shared her life story as a representation of the American dream during the Democratic National Convention. She criticized Donald Trump's leadership failures, attributing them to the loss of lives and jobs. Barack Obama also spoke at the convention, highlighting Trump's mishandling of the coronavirus pandemic and its devastating effects on the country. The night featured numerous female speakers, with Harris specifically targeting women, young Americans, and voters of color in an effort to secure support for Biden in defeating Trump. Harris expressed concerns about the chaos, incompetence, and callousness of the current administration. She stated that the current situation is significant and we can improve our circumstances. She criticized the president for using tragedies for political gain and expressed confidence in Joe Biden's ability to turn challenges into opportunities. She made these remarks from a simple hotel ballroom in Biden's hometown of Wilmington, Delaware. According to opinion polls, Biden is currently leading Trump, especially among female voters. Throughout the convention, Democrats have been directly appealing to female voters, emphasizing Biden's role in co-sponsoring the significant Violence Against Women Act of 1994 and his plans to strengthen childcare and protect family healthcare provisions. Obama, who had Biden as his vice president from 2009-2017, expressed his disappointment that Trump did not take his job seriously, failed to understand the responsibility of the office, and lacked respect for American democracy. Obama criticized Trump sharply, stating that he has not grown into the role of president and cannot do so, with severe consequences such as millions of lost jobs. "Our worst impulses unleashed, our proud reputation around the world badly diminished, and our democratic institutions threatened like never before," Obama stated. The choice of a running mate is particularly important for Biden, who at 77 years old, would be the oldest person to become president if elected. Speculation about Biden serving only one term due to his age has made Harris a potential top contender for the nomination in 2024. Harris, 55, was named as Biden's running mate last week to go up against incumbents Trump, 74, and Vice President Mike Pence, 61. Hillary Clinton, the 2016 Democratic presidential nominee, who lost to Trump, shared at the convention that she regularly hears from voters who regret supporting Trump or not voting at all. Clinton emphasized the importance of voting in the upcoming election, stressing that it cannot be another missed opportunity. She urged people to vote as if their lives and livelihoods depended on it. Clinton also pointed out that Biden must win decisively, as winning the popular vote may not guarantee victory in the Electoral College. She warned that Biden and Harris could potentially win by a significant margin in the popular vote, yet still lose the presidency. Listen to me. We need a large number of votes to prevent Trump from winning through deceit or theft. Democrats are concerned about Trump's attacks on mail-in voting and changes to the US Postal Service that could impact mail delivery during the election. Postmaster General Louis DeJoy, a Trump supporter, has agreed to postpone these changes until after the election. Democrats are also highlighting Trump's policies on immigration, gun control, and climate change. Nancy Pelosi, the first woman Speaker of the US House of Representatives, expressed her concerns about Trump's disregard for facts, working families, and women, both in his policies and conduct. She emphasized the importance of women succeeding for America to succeed. US Senator Elizabeth Warren, a prominent progressive who competed against Biden in the 2020 primary, discussed Biden's plans to make childcare more affordable, calling it essential for working Americans. She highlighted the need to view childcare as a fundamental part of the nation's infrastructure. Kamala Harris, in her upcoming speech, will likely share her personal story as a child of immigrants and her accomplishments in breaking gender and racial barriers throughout her career. She became well-known in the Senate for her thorough questioning of Trump nominees, including Supreme Court Justice Brett Kavanaugh and Attorney General Bill Barr. The Republican National Convention, which will also be mostly virtual, is scheduled for next week.
