Marriage Gap, one more time

From a Democratic group working to get more single women to show up to vote, Voter Participation Center, on the 2012 election:

As more data is available from the exit polling, the extent of the marriage gap – the differences in candidate choice between married and unmarried women – becomes more obvious and undeniable. And as this chart make clear: the marriage gap transcends all racial, age, income, education and other distinctions. Young or old, rich or poor, white, black or Hispanic, unmarried women voted overwhelmingly in 2012 to reelect President Obama.

I don't like how the righthand "Marriage Gap" column is double-counted, although that seems to be the standard way that gaps get talked about. People like double-counting because it makes whatever gap you are worked up over seem too huge to grasp mentally --  e.g., the Race Gap in Texas was something like 150 points!

But even if you divide the Marriage Gap figures by two, the way I like, they're still a big deal.
