"But what might make 2012 different is the edge Latinos could give President Barack Obama and the Democrats in battleground states which aren’t thought of as immigration portals or left-leaning strongholds.
The 2010 Census revealed that in the past decade the adult Latino population has nearly doubled in Nevada, Virginia, and North Carolina. Also, it's increased by 60 percent or more in two Midwestern battleground states, Indiana and Ohio.
Obama won all five of those states in 2008 — two of them by very narrow margins — and they are likely to be decisive in next year’s balloting."
