Supreme Court Chief Justice John Roberts Jr. touched a nerve in Massachusetts on Thursday when he asserted that the Bay State has the worst record in the country on voting and registration by African-Americans. His remarks came as the high court was hearing arguments on a case involving the Voting Rights Act, which is designed to promote equal access to polling places.

Roberts asked Donald Verilli Jr., the solicitor general for the Justice Department, whether he knew which state had the worst ratio of white voter turnout to African-American turnout. When Verilli said he didn’t, Roberts told him it was Massachusetts. He added later that Massachusetts also has the greatest racial disparity in registration.

The Globe jumped on the story and hit paydirt when Massachusetts Secretary of State William Galvin said Roberts had his facts wrong. In high dungeon, Galvin said he was calling out Roberts and his “effort to make a cheap-shot point.” The Globe found plenty of other locals who attacked Roberts’s remarks as unsubstantiated.

Unfortunately, there’s no good data in Massachusetts on voting by race because state officials don’t track that information. The chief justice’s comments appear to have been based on a US Census survey (see Table 4b) from the 2010 election that showed a paltry 29.1 percent of blacks voted in Massachusetts.

But the Census survey has a number of problems. First, it has a large margin of error on black voting. Second, it’s risky to rank states on black voting, as Roberts did, because the black population in 17 states was so small that it was impossible to make any statistical comparisons. The datapoint Roberts seized on was the percent of blacks in Massachusetts who voted. According to the Census survey, the 29.2 percent figure had a margin of error of 9.2 percent. The Census survey indicates 39.3 percent of black voters in Massachusetts who are citizens cast ballots.
