ABC News’ Rick Klein reports: A group of liberal activists is teaming up with a Latino organization to run Spanish-language radio ads targeting Republican lawmakers over GOP opposition to Judge Sonia Sotomayor. The ad places Rush Limbaugh front and center in the debate over Sotomayor’s Supreme Court confirmation hearings. It quotes Limbaugh as calling Sotomayor a “bigot” and a “racist,” and refers to Limbaugh as one of the “Republican leaders” who are attacking the judge. “It’s insulting to all Latinos and Americans,” the ad says in Spanish. The ads — organized by Presente.org and the Progressive Change Campaign Committee — are running in eight heavily Latino congressional districts in Florida, according to organizers. The districts include four now held by Republicans, including top Democratic targets Rep. Adam Putnam, R-Fla., and Rep. John Mica, R-Fla. The effort is part of a broader campaign by progressive groups to capitalize on the publicity over the Sotomayor confirmation hearings to solidify Democratic gains among Latino voters. As ABC’s Viviana Hurtado is reporting, Latino organizations are organizing confirmation-hearing “fiestas” to celebrate the nomination — and to serve as organizing hubs if community leaders perceive bias in the hearings that they choose to respond to.
