With an eye toward the 2024 campaign, President Joe Biden on Thursday ventured to Florida, a state defined by its growing retiree population and status as the unofficial headquarters of the modern-day Republican Party. The president sees a chance to use Social Security and Medicare to drive a wedge between GOP lawmakers and their base of older voters who rely on these government programs for income and health insurance. Biden is trying to lay the groundwork for an expected reelection campaign announcement this spring. White House aides have been using the votes and words of Republican lawmakers to make their case that Social Security and Medicare benefits are under threat, while GOP leaders say their statements are being mischaracterized.
