The Democratic National Committee is intensifying its use of the American Jobs Act to shore up support among President Obama’s base, even as Obama says the bill is not about political posturing.

The DNC today unveiled a new Spanish-language TV and radio ad to air in three battleground states — Nevada, Colorado and Florida — touting the act’s benefits to the Hispanic community.

“In the face of Republicans, the president can’t do it alone,” the Spanish-speaking narrator tells the audience, seeking their support. “Read the plan. Stand together for more jobs.”

DNC chairwoman Debbie Wasserman Schultz of Florida said in a statement that the jobs bill would be a boon to Hispanic construction workers, of which there are 2.77 million in the United States, Hispanic small business owners and jobless Hispanic veterans.

“The Republican Party is offering no new solutions for Hispanics,” Wasserman Schultz said. “They simply want to double down on the failed policies that brought our economy to the brink of a depression and hurt millions of American families, including far too many Latinos.”

Obama won 67 percent of the Hispanic vote nationwide in 2008. His campaign believes turnout among Hispanics in battleground states could a key factor in 2012.

The new ads follow a broader Democratic media blitz on Obama’s jobs plan launched earlier this month in eight battleground states: Colorado, Florida, Iowa, Nevada, New Hampshire, North Carolina, Ohio and Virginia.

A DNC website developed in conjunction with the bill, americanjobsact.com, also outlines its projected impact on five constituencies deemed critical to Obama’s 2012 campaign:  women, Latinos, African-Americans, veterans and low-income families.  The White House has also distributed fact sheets on the legislation tailored to the same audiences.

Meanwhile, Republicans have been also courting Hispanic voters with Spanish-language ads in Colorado, Nevada, Florida and New Mexico, hoping to capitalize on economic malaise to draw support away from Democrats.

The Republican National Committee says it plans a new campaign targeting Hispanic voters “very soon.”

“We feel the economic issue right now is huge with the Hispanic community and we need to make sure our side is visible,” RNC spokeswoman Kirsten Kukowski said.
