Meh. All Trump has to offer poor people (black, white, or otherwise) is a double down on trickle down. Hasn't worked for the last 30 years, won't work now.
Obama got health insurance for many thousands of poor people which is a real and substantial improvement in their lives (please note this is not an endorsement of the ACA as a whole, just an observation of one of its salutary effects that is applicable to the current discussion of "what have you done for me lately"). Unfortunately, many thousands more poor people, disproportionately black, live in Republican-led states that refuse to expand Medicaid. The many flaws in the ACA leave an open question as to whether the gains delivered to date are sustainable, but that's not the question at hand.
Since 2010, the federal government has been so gridlocked that any improvement/worsening in the lives of the poor has been delivered by general economic factors, not federal government policy. Outside of ACA, state-level policies have had much more impact on the lives of poor people for the past 8 years. Partisans can give credit or blame on that score however they wish. In NC, poor people have not seen a meaningful increase in income or quality of life. However, their state taxes have actually increased while the state taxes of the wealthiest have been substantially cut, and their access to government benefits has been substantially reduced. Thanks, Obama?
