In this year's presidential campaign, $11 million has been spent so far on ads targeting Hispanics, according to ad-tracking firm Kantar Media/CMAG.
That's eight times the amount spent four years ago on Spanish-language ads, and it's focused in just a handful of battleground states: Florida, Nevada, Colorado and, perhaps most surprisingly, North Carolina.

Republican presidential candidate Mitt Romney and his wife, Ann, at the Church of Jesus Christ of Latter-day Saints in Wolfeboro, N.H. The candidate regularly attends church, but he rarely invokes religion on the campaign trail.
Religion used to be everywhere in the presidential elections. George W. Bush courted conservative believers in 2004. In 2008, Sarah Palin excited evangelicals and — unexpectedly — so did Barack Obama.
What a difference a few years make. In 2007, then-candidate Obama used evangelical language to describe his Christian conversion: He was a young, secular community organizer who occasionally visited the local Chicago church, when one day he walked to the front of the sanctuary and knelt before the cross.
Housing continues to be a big issue for the economy, and for many voters. But so far it hasn't been a major issue in the presidential campaign. Perhaps that's because both sides agree that there's no easy fix for the problem of millions of troubled mortgages.
Cathy Busby and her husband co-owned a realty office in Denver when they bought their house in 2006. The next year, the market for houses dried up, leaving them with little income as their house lost value.
Now, she says, she considers herself "poverty level."
Republicans are still within reach of a big political goal this year: retaking control of the Senate. They lost the majority in 2006, in part because of the razor-close victory of Democratic challenger Jon Tester in Montana.
Now, Tester is the incumbent facing a tough challenge of his own. And if he's going to win re-election, he has to turn out a lot of younger voters, the way he did in 2006. And on that front, he does have some allies.

This is Need for Speed: Carbon, one of 18 games that the Obama campaign advertised in during the 2008 campaign. This year, President Obama is back at it, running ads in Madden NFL 13, on the free online game site Pogo.com, and in mobile games like Tetris.
Here's something President Obama and Mitt Romney agree on: America's tax system is too complicated. Both men have outlined changes that are broadly similar, but with some important differences.
Today's tax code is like a department store, where the price tags are high, but there are lots of coupons, sales and weekend specials. That creates some inequities. Just as shoppers can pay different prices depending on which day they buy, taxpayers with the same income can pay very different rates depending on which deductions they qualify for.
