At least some of the Trump voters think Trump is all lies, and voted for him anyway. NPR was following up with some people who voted for Trump and are now terrified that the Affordable Care Act will be repealed. They were asked if they had not heard Trump's plan to demolish it. They had, but one woman felt that *no* campaign promise Trump made was in any way believable, so she didn't worry at voting time that her family (in which her husband is on a waiting list for a liver transplant, which will cost millions) would lose their ACA insurance. They voted for Trump because they own a small business, and wanted a business person in the White House.
As it happens, it seems to me that health insurance is completely off Trump's radar right now. It's the Republicans in Congress who will seal her husband's fate.
