After the U.S. Senate failed to extend enhanced Affordable Care Act tax credits, health insurance premiums are set to soar for millions of Americans, including nearly 5 million Floridians who rely on those subsidies. Lawmakers rejected both Democratic and Republican proposals to address the expiring credits, leaving coverage less affordable as the year ends. Advocates warn that without action, many people will face higher costs or lose coverage altogether. The fight over health care affordability continues in Congress.
