I have to be honest: Your question sounds like satire in light of all that is going down.
I will just sample Georgia since it is the most visible:
"Georgia, a state where 31 percent of the population is African American and 9 percent is Latino, has 214 fewer polling places. Georgia stands out because its counties have closed higher percentages of voting locations than any other state in our study. The top five closers of polling places by percentage were Georgia counties: The top three counties in the state were Lumpkin (89 percent closed); Stephens (88 percent closed); and Warren, which is 61 percent African American (83 percent closed). Bacon County, which is 15 percent African American, and Butts County, which is 28 percent African American, tied with 80 percent closed. Seven counties with major polling place reductions now have only one polling site to serve hundreds of square miles. In a February 2015 memo, the office of Brian Kemp, who was then serving as Georgia’s secretary of state, encouraged counties to consolidate voting locations. He specifically spelled out twice — in bold font — that “as a result of the Shelby vs. Holder [sic] Supreme Court decision, [counties are] no longer required to submit polling place changes to the Department of Justice for preclearance.”

The above is just about poling places. Its not even considering ending of seemingly little things like Sunday voting.
Georgia’s Proposed Voting Restrictions Will Harm Black Voters Most
Also:
The rise of voter numbers comes even as Georgia Republicans work to recast voting laws in the state. In the last two years, the state's GOP-led legislature has passed two major voting bills that activists have said would hurt communities of color. The first, SB 202, created new voter identification requirements for absentee ballots, empowered state officials to take over local elections boards, limited the use of ballot drop boxes and made it a crime to approach voters in line to give them food or water.
This year's bill created an election police force with the power to investigate election fraud. Both pieces of legislation were signed into law by Republican Gov. Brian Kemp.
The Rev. Zachary Holmes spent part of last weekend assembling people to head to the polls ahead of Tuesday's primaries. But the church parking lot was a lot less crowded than it normally would have been.

SO TO ANSWER YOUR QUESTION:
enough people are effected by it that 33% voted that it is a pressing issue. I don't have the numbers because how would I?
-Black voter may not bother because his local poling place closed.
-He may get his ballot rejected.
-He may miss a deadline for various reasons (Slow USPS affected a handful of votes last go-round)
Its like unemployment numbers...you have an official number and then folks who gave up and now are no longer counted. Fact is, this is a big deal and a direct punishment for last years election results. If Black folks can not vote for representation, there are no reparations.
