http://www.politico.com/magazine/story/2015/05/the-gop-is-dying-off-literally-118035.htmlBy combining presidential election exit polls with mortality rates per age group from the U.S. Census Bureau, I calculated that, of the 61 million who voted for Mitt Romney in 2012, about 2.75 million will be dead by the 2016 election. President Barack Obama’s voters, of course, will have died too—about 2.3 million of the 66 million who voted for the president won’t make it to 2016 either. That leaves a big gap in between, a difference of roughly 453,000 in favor of the Democrats.But also more importantly:
In 2012, there were about 13 million in the 15-to-17 year-old demo who will be eligible to vote in 2016. The previous few presidential election cycles indicate that about 45 percent of these youngsters will actually vote, meaning that there will about 6 million new voters total. Exit polling indicates that age bracket has split about 65-35 in favor of the Dems in the past two elections. If that split holds true in 2016, Democrats will have picked up a two million vote advantage among first-time voters. These numbers combined with the voter death data puts Republicans at an almost 2.5 million voter disadvantage going into 2016.
