Early in the presidential campaign, Hillary Clinton proposed a package of ideas aimed at helping adult children who care for aging parents and other relatives. Yesterday, Donald Trump embraced a similar idea. Family caregiving, it seems, is going mainstream.

It is striking that both Clinton and Trump are talking about an issue that until now has flown far below the political radar. Best I can tell, this is the first time any major party candidate for president, let alone both, has proposed ways to help caregivers.
