Once upon a time political science research suggested that there was no partisan gap between voters and non-voters. Now there's an ENORMOUS one. It might not be a big concern with likelihood of voting wasn't strongly correlated with income, but, well, it is. So what we have is a huge class bias in U.S. elections. One the Republicans are trying to exacerbate. Frankly these sorts of inequalities raise serious questions about the legitimacy of the American political regime.

And in case you were wondering, if it were Romney that was favored by non-voting, I'd still be annoyed.
