Suburbs in South Florida that have swung toward former President Donald Trump are where the “Obamacare” health care program is more popular than anywhere else in the country. Trump has vowed to renew efforts to repeal and replace former President Barack Obama's 2010 health care overhaul if he's reelected. That would be felt heavily in the region and could possibly reverse some of the GOP shift among South Florida’s Latinos. President Joe Biden’s reelection campaign has already seized on Trump’s statements about the Affordable Care Act as part of its broader efforts to shape the widely expected 2024 rematch between him and Trump.
