Univision announced Tuesday it will not air any ad spots from a conservative Latino group that is telling voters not to go to the polls on Election Day.

Latinos for Reform launched a national ad campaign targeting Hispanic voters who they say have been betrayed by members of Congress delinquent on delivering immigration reform promises pledged by President Obama during the 2008 campaign.

"It's an election year, so perhaps we shouldn't be surprised to hear promises about immigration reform," said LFR President Robert Deposada. "What is surprising, however, is that these politicians really believe that they can continue to make these same promises during every campaign season without ever delivering on them -- and that we continue to allow it."

But Univision, which would be a huge target audience for the Spanish-language version of the ad, tweeted that it will not air any spots from the group related to voting.

"Prides Itself on Promoting civic engagement & encouraging Hispanics to vote. Join us," reads one tweet.

Deposada, a former GOP operative, and his group were swiftly admonished by the Latin Chamber of Commerce, according to the Las Vegas Review-Journal.

But LFR Vice Chairman Naomi Lopez-Bauman said that both Democrats and Republican leaders have betrayed Hispanics. She encouraged Latinos to vote in local and state elections, but to skip congressional races.

""If we sit idly by and vote for the same lawmakers that ignore us once they are in office, we will just get more of the same shabby treatment. If, however, we don't vote for politicians who don't deliver on the promises they make to our communities, then they will be forced to stop taking our support for granted," she said.
