Glen Bolger and Neil Newhouse: "Democrats like to accuse Republicans of being bad at science, but in fact we're really bad at math. Winning in a non-presidential-turnout year, when older and white voters make up a larger percentage of the electorate, should convince no one that we've fixed our basic shortfalls with key electoral groups, including minorities and younger voters." "Assuming that the Democrats replicate their 2012 electoral success with minority voters two years from now, and assuming that Hispanics grow as a percentage of the overall electorate, which they will, we calculate that Democrats will already have almost half (24 percent) of the votes they need to win a majority of Americans in 2016.
