You aren’t really good with math are you? Luckily, I am, so let me explain it to you. A 50% increase from basically nothing, is, well, insignificant. If the Republican candidate got that overall 4% bump every in every future presidential election, they would get the majority of the black vote—in the 2060 election. So check back with me in 40 years.
  Trump is the biggest crook out there and you know that. The legal firestorm coming his way in a little over two months will dwarf anything you’ve seen so far.  And I didn’t see your explanation for why Trump’s support among white males went down this time.

Actually, I am very good with math. One of my previous job titles was Statistical Process Control Coordinator. If you do not know what statistical process control is, then look up W. Edwards Deming, who taught a four day seminar that I attended, which was the beginning of my training. I later received three weeks of training in Advanced Statistical Process Control Methods. I was also an engineering major who worked for 20 years as a registered professional engineer in Kentucky before switching to a career in IT.

Your math skills may be superior to mine but I am not seeing any evidence of that being the case in your posts.

You assume that Republican's inroads into the black electorate would be linear over a 40 year period. If future Republican presidents' policies benefit blacks to the same extent as Donald Trump's policies have, a growth rate of 50 percent per election is more likely than a "bump" of 4 percent per election.

Also, the accuracy of the numbers you cited is very questionable. Exit polls have proven very unreliable over the past two presidential elections because conservatives and Trump supporters are much less likely to participate in polls. Then, there is the matter of Democrats cheating in the inner cities, which dilutes the estimated support rate for Republicans among blacks.

BTW, the estimated rate at which black men voted for Donald Trump is 18 percent. That is why BLM has targeted black Trump supporters with violence and derision. Successful black men are beginning to abandon the Democrat party.
