The Real Mitt Romney has launched a bid to win over Latino voters, from noting that his father was born in Mexico to airing a new Spanish-language ad in Florida. But he's not getting any help from @MexicanMitt, a ribald and unsympathetic Latino alter ego someone has launched on Twitter.

@MexicanMitt started tweeting yesterday, kicking off the account by saying, "Corporations are peoples, my amigos!" "You know you can tell I am Mexican?" Mexican Mitt asked later. "Because I take the Americans jobs!"

After the real Romney's victory in Tuesday's New Hampshire primary, Mexican Mitt exclaimed, "I won, cabrones!" As the GOP frontrunner made his way down to the next primary state of South Carolina, Mexican Mitt tweeted, "Esta noche voy a el Sur de Carolina. Carolina es mi otra esposa, guey!" - meaning, "Carolina is my other wife!"

The tweets from Mexican Mitt have come one after another in the past two days.

"I am so Mexican I don't have a Super PAC, I have a Super PACO!" he tweeted.

Taking aim at one of Romney's rivals, Mexican Mitt said, "Niut Gringorich, shut up about my business practices - you sound like a pinche OCCUPY HIPPIE!!"

The Twitter alter ego comes as Romney makes a serious push to court Latino voters, the nation's fastest-growing voting bloc and a minority that could prove crucial in upcoming GOP primary states such as Florida and Nevada. At a campaign stop in Rochester, N.H., on Sunday, Romney referenced the fact that his father, George, was born in Mexico and came to the United States at age five.

Despite his distant Mexican roots, though, Romney has come under fire for his immigration stance. The former Massachusetts governor vowed that as president he would veto the DREAM Act, the Democrats' measure to provide a path to citizenship for some undocumented children of immigrants who attend college or serve in the military.

That stance, understandably, alienated some possible Latino supporters. Juan Rodriguez, a businessman in Des Moines, said he would not support Romney because of his threatened veto, while Esteban Lopez, a Goffstown, N.H., resident who will vote for the first time in the general election later this year, said he too would not back Romney.

"I work in education and I know first-hand how important the DREAM Act is for Latino youth, for kids who are in this country without having taken part in the decision to come here," Lopez said. "The short answer is, I wouldn't vote for Romney."

With nearly 500 tweets in the past two days, Mexican Mitt - who claims to be "the most Mexican man in the world" - already has over 1100 followers.
