By Emily Alpert Reyes, Los Angeles Times Medicare. Drug costs. The fate of the Affordable Care Act. Health care — and who would handle it best — has continued to be contested turf in the final weeks of the presidential campaign. Polls show that Americans have ranked health care costs high on the agenda for national leaders. It’s little surprise, then, that both Vice President Kamala Harris and former President Trump have pledged to bring down the cost of prescription drugs and protect Medicare. But in a campaign season that has been light on detailed proposals on health policy — which has often taken a back seat to other issues — “you have to look more at their records,” said Larry Levitt, executive vice president for health policy at KFF, an independent health policy research and news organization. “And if you look at their records, Harris and Trump are polar opposites,” starkly split on the role that government should play in health care and the trade-offs surrounding its spending, he said.
