Fewer Americans lack health insurance — but the gap remains wide, especially in some pro-Trump states.
The number of uninsured declined to 28.3 million in the first quarter, down from 29.3 last year — and 48.6 million in 2010, the year the Affordable Care Act was signed into law by then-President Barack Obama, according to data from the federal Centers for Disease Control and Prevention.
The distribution, however, is uneven with data for south central states — Arkansas, Louisiana, Oklahoma and Texas — showing almost a quarter of adults lacking health care coverage. President Donald Trump, who has opposed Obamacare, won those four states in the 2016 presidential election.
