Actress Eva Longoria is raising her political profile as a newly-appointed co-chair for President Obama's re-election campaign, appearing on a national cable channel Monday afternoon to put some star power behind Democrats' pitch to Latino voters.

The Hollywood A-lister is one of seven Latinos appointed as co-chairs, or surrogates, for Obama's campaign, which Longoria said was not orchestrated by accident. The Latino community and women voters are key constituencies to Obama's bid for a second term. The actress, who campaigned for Obama back in 2008, said she will play a much more active role this time around in engaging and mobilizing voters like her.

"There is an attack on women's healthcare," Longoria told MSBC in an interview, adding that Republicans are now aiming to "dismantle" many of the recent gains for women. Longoria's home state of Texas, she noted, has the highest number of uninsured women in the country, as well as the highest number of uninsured residents.

"It's pretty clear for women who's on their side regarding healthcare issues," Longoria said, alluding to Obama.

Longoria also took aim at GOP frontrunner Mitt Romney, who fresh off of a primary win in Puerto Rico declared that "conservative principles and Latino voters go together."

"He makes a huge generalization there," the actress bristled. "Of all the candidates, Mitt Romney is probably the one on the wrong side of every issue pertaining to Latinos," which, she says, include education, the economy and healthcare access.

Longoria called Romney's stance on immigration reform "dangerous," ans said the addition of Kansas Sectary of State Kris Kobach, the author of Arizona's anti-immigration law, to his campaign team would be "polarizing to Latinos."

Longoria also sought to shoot down the "misconception" that Latinos favor illegal immigration, which, she says, is not true.

She conceded that some Latinos are disappointed with Obama, but she affirmed that he has done what he could with having "his hands tied by Congress." (Longoria did not mention that Democrats held majorities in both houses of Congress during the first two years of Obama's term.)

"Obama is the only one who understands that the success of the future in America is intricately tied to the success of the Hispanic community," Longoria said. "But he can't do it by himself."
