Alex Keyssar in Harvard Magazine: “How many people will actually be prevented from casting ballots by these laws in November? What impact will these laws have on participation? The straightforward answer is that none of us (scholars, commentators, politicians) really know—because the laws are recent and measuring their impact is difficult. (We should know more after November, since several studies will be conducted during this election.) The number is unlikely to be huge, particularly since various pro-voting-rights groups (as well as the Democratic party) will work hard to help people get their ID documents. But it could certainly be large enough to affect the outcome of close races for Congress and even for the presidency.”
