That's the gist of this article by John Harwood. Here's an excerpt:
Exit polls showed that just 10 percent of Trump's votes came from Americans earning $200,000 or more. Yet those voters would derive all benefits from the repeal of the two individual tax hikes targeting them: a 0.9 percent tax on their earnings, and a 3.8 percent tax on their investment income. An even smaller group, the top 1 percent of earners, would receive an average tax cut of $33,000, according to the Tax Policy Center. The top 0.1 percent of earners would receive an average tax cut of $197,000. *** Whites aged 45 or older provided 56 percent of Trump's votes. Older Obamacare enrollees would be hit particularly hard by the House bill because it curbs age-based insurance subsidies. Enrollees aged 55 to 64, the Cutler study found, would face higher costs averaging $6,971 in 2020.
