The second round of presidential debates and the single debate for the candidates' running mates will have different formats than the first fiery head-to-head between Democratic nominee Hillary Clinton and Republican nominee Donald Trump.
The Oct. 9 debate will be in a town hall setting with an audience of uncommitted voters asking questions directly to the candidates.
Potential health topics that have not been touched on yet include prescription drug prices, the stability of the Affordable Care Act exchange marketplaces and the future of the ACA in general. Trump has vowed to repeal the law but has not said what he would put in its place. Clinton is campaigning on the successes of the law and her plans to improve it.
