Calls from some Congressional Democrats persist for President Joe Biden to step aside and allow a new leader, despite a temporary pause; Biden faces scrutiny over his debate performance and age-related vulnerabilities, prompting concerns about his re-election prospects. Curtis Wilkie, a retired journalist, expresses doubts about Biden seeking a second term, citing age-related frailties and vulnerability to Donald Trump's return. Biden, after addressing concerns about his candidacy with a positive outlook, is now adopting a more combative stance, privately conveying that discussions about his future are over and aiming to quell dissent within the Democratic Party to focus on defeating Trump, tightening his circle of supporters. There are growing organized efforts among Democrats for Biden to step down, including concerns from various quarters, such as the media, elected representatives, and financial backers, about his age and ability to govern effectively.
