(CNN) - The Spanish language television network Univision is pulling television and radio ads from the group Latinos for Reform, which urge people not to vote.
In the ads, which were set to begin airing on Univision on Thursday, a Spanish speaking narrator cites the Obama administration's lack of action on immigration reform and tells viewers "This November we need to send a message to all politicians. If they didn't keep their promise on immigration reform, then they can't count on our vote."
"Don't vote this November," the narrator says as a bell tolls. "This is the only way to send them a clear message, you can no longer take us for granted. Don't vote."
Robert Deposada, chairman of the activist group Latinos for Reform and a conservative political analyst for Univision, told CNN that a sales representative called him Wednesday and said that the "concept of the message was not in line with their views."
"Univision will not be running any spots from Latinos for Reform related to voting." Univision spokeswoman Monica Talan confirmed in an email to CNN.
"It is also important to clarify that while Mr. Robert de Posada has on occasion provided political commentary on Univision, representing one of various points of views, he is not in any way affiliated with Univision. Univision prides itself on promoting civic engagement and our extensive national campaigns encourage Hispanics to vote."
Deposada said he believes Univision execs "didn't want to set Harry Reid off," and that he has now cancelled his appearances on the network.
According to Deposada, a radio version of the ad ran about five times on Tuesday but the television version never aired.
The ad, which was also posted online, features the iconic 'Change' poster of Barack Obama from the 2008 presidential election and pictures of members of the Democratic leadership including Senate Majority Leader Harry Reid, Speaker of the House Nancy Pelosi, Sen. Barbara Boxer (California), Rep. Maxine Waters (California) and Rep. Charles Rangel (New York).
Deposada said he is now reassessing the group's strategy, but insists he has not given up in pushing the message of the ad he produced, which is that President Obama and Democratic leaders in Congress did not keep their promises to the Hispanic community.
He calls it a campaign to "highlight the empty promises," especially on illegal immigration.
About 6.5 million Hispanic voters will likely cast their ballots this year, according to the National Association of Latino Elected and Appointed Officials nearly 1 million more than in the last midterm elections in 2006.
