Miami Herald: Robo calls paint Romney as pro-Castro, says Cardenas
Mitt Romney' s state chairman Al Cardenas says robo calls portraying Romney as soft on Castro have been going out this afternoon to Miami voters.
The calls almost immediately following appearances by diplomat Roger Noriega praising the candidate on Spanish-language radio, said Cardenas, who called the calls "dirty pool" and "despicable."
He said he's not sure who is behind the calls but said "we can only assume it's one of our opponents."

St. Petersburg Times: Anti-Romney pushpolling
Romney campaign is getting reports of anti-Romney pushpolling in Orlando, Fort Myers and West Palm Beach, the calls started this morning.
The poll calls are saying that Romney never supported Bush tax cuts, supports tax-payer funded abortions and wants relations with Fidel Castro. Some calls have targeted the Cuban community in South Florida and are in Spanish, said Al Cardenas, Romney's Florida chair.
"These are clearly negative and false attacks against Gov. Romney by a flailing campaign desperate to change the dialogue on issues that matter most to Florida voters like lower taxes, less government and stronger families," said campaign spokeswoman Kristy Campbell.

Funny, I never hear the news reporting on pushpolling calls from Mitt Romney or in support of Mitt Romney.
