Florida Governor Ron DeSantis kicked off his 2024 presidential campaign on Tuesday with his first public appearance in Iowa, hoping to persuade Republicans to favor him over former President Trump. The field is expected to grow bigger, as reports suggest both former Vice President Pence and former Governor Chris Christie will enter the primary race as early as next week. On the Democratic side, a recent poll found President Biden’s support lacking, with his primary challengers, Robert F. Kennedy Jr. and Marianne Williamson, polling at 16 percent and 8 percent, respectively. National Political Correspondent for POLITICO, Meridith McGraw, joins the Rundown to talk about why the Republican party has shifted away from its initial support for DeSantis and what the Democratic challengers poll numbers tell us about President Biden's weaknesses heading into 2024. The Center for Disease Control and Prevention reports that the world is currently experiencing its worst outbreak of H5N1, commonly known as bird flu, resulting in the deaths of an estimated 58 million birds. After going through the COVID-19 pandemic, health officials have expressed confidence that the country could manage this virus if it began to spread from person to person. However, some scientists believe this avian influenza has the potential to become the world’s most deadly pandemic. Former CDC Director, Dr. Robert Redfield, joins the Rundown to discuss why the deadly potential of the bird flu further emphasizes the dangers posed by gain-of-function research and what the United States must be doing now to prepare for the world’s next pandemic. Later, public health expert and Professor at Johns Hopkins University Dr. Marty Makary explains how COVID-19 impacted Americans’ faith in health officials.
