About 11 million Hispanics voted in the 2012 presidential election, fewer than half of those who were eligible. Activists in both major political parties have been trying to increase that number, through voter registration drives and appeals over issues like immigration and wage stagnation on the left, and economic freedom on the right.

Now, so is Univision.

The company, including its top-rated Spanish-language network and many subsidiaries, is making an ambitious nationwide effort aimed at registering about three million new Latino voters this year, roughly the same number who have come of voting age since 2012.

The initiative will entail an aggressive schedule of advertisements on all of Univision’s video and digital platforms, including 126 local television and radio stations and the sports channel Univision Deportes. Station managers will exhort their audiences in old-fashioned editorials, a comprehensive online voter guide will be updated throughout the election season, and the media company will use the kinds of grass-roots organizing events usually staged by candidates — town-hall-style forums and telephone banks — to try to turn its viewers into even more of a powerhouse voting bloc than it already is.

“The rule is no one can make it to the White House without the Hispanic vote,” said Jorge Ramos, the network’s news anchor. “That’s why Latino registration is incredibly important. Just a few votes in Nevada, Florida and Colorado could make or break any candidate.”
