Self-help author Marianne Williamson, whose 2020 White House campaign featured more quirky calls for spiritual healing than actual voter support, was the first Democrat to formally challenge President Joe Biden for the 2024 presidential nomination. The 70-year-old onetime spiritual adviser to Oprah Winfrey should provide only token primary opposition � a testament to how strongly national Democrats are united behind Biden. Still, she tweaked the president, a longtime Amtrak rider, by officially launching her second presidential campaign at the ornately marble-columned presidential suite at Union Station, Washington’s railway hub. Red, blue and black campaign signs for Williamson feature the dual slogans "A New Beginning" and "Disrupt the System."
