Low information voters are legion — a potential majority too.
Based on the 2008 & 2012 elections, I’d say they must be a plurality by now (factoring in the government worker vote that went to Obama in both elections as INFORMED voters choosing more goodies for themselves). I work with old white women who do this; they are insulated from the tax burdens by their alimony payments (though they are now finding themselves unable to afford retirement).
