File this under boring and probably unimportant. The US Census Bureau recently reported voter turnout rates for the 2012 presidential election. They concluded that the black turnout rate was for the first time higher than the white turnout rate. Now Pew comes on the scene with a spoiler, and it boils down to this: states with a proportionally higher black population tended to over-report voting rates. This is known because you can compare the actual voter turnout numbers with the number of people in each state who say, in response to a poll question, that they voted.
We don't really care, and the fact remains that black turnout has steadily increased every election and that black and white voting rates are well within the margin of error of each other. What's important here is that Alaskans - paragons of honesty that we are - were one of just eleven states where in 2012 more people actually voted (60.7 percent) than said they voted (58.4 percent).
Or maybe we lie too, but just in the other direction. Makes as much sense as anything else. In the Pew analysis, available as an Excel file, Alaskans under-reported their voting behavior by the third largest margin, tied with New Hampshire and trailing Florida and Maryland. Go figure.
