In 2012 Barack Obama defeated Mitt Romney by 4.96 million votes, and according to Latino Decisions analysis of the election returns and Latino voting data, Latinos provided Obama with a 5.8 million vote margin. If the Republicans could have won 40% of the Latino vote in 2012 that would have erased 3.6 million net votes – or 72% of the 4.96 million they lost by. Republican don’t need to win the Latino vote outright, they just need to stop losing it so badly. Although Latinos are not the only demographic that Republicans need to improve their showing with, they represent the single largest bloc of voters who are movable. An estimated 11.2 million Latinos cast a ballot in 2012 according to the Census, and more than 12.5 million are likely to cast a vote in 2016, further increasing the share of all voters who are Latino, nationally and in key states.
