Americans who swept President Trump to victory — lower-income, older voters in conservative, rural parts of the country — stand to lose the most in federal healthcare aid under a Republican plan to repeal and replace the Affordable Care Act, according to a Times analysis of county voting and tax credit data.

Among those hit the hardest under the current House bill are 60-year-olds with annual incomes of $30,000, particularly in rural areas where healthcare costs are higher and Obamacare subsidies are greater.
