Pro-Obama Groups Launch $4 Million Ad Blitz Attacking Romney in Spanish

The 2012 presidential election will most certainly be won or lost based on American voters' perception of the economy and which candidate is the more trusted steward to lead the country to sturdier economic ground.

But it will also be about the country's rapidly evolving demographics.

One week after Mitt Romney unveiled the leadership of his campaign's Hispanic outreach, two pro-Obama groups are launching a major offensive aimed at defining Romney in a negative light to U.S. Hispanics.

The pro-Obama super PAC, Priorities USA, and the Service Employees International Union are using Romney's own words from the 2011-2012 Republican nomination season in a new round of television and radio ads going up today and running through the summer in Florida, Colorado and Nevada, three critical battleground states where Hispanic voters will have a major impact on the outcome. The groups are spending $4 million on the ad campaign.
