A new Spanish-language commercial by the Romney campaign links Obama to Latin American leaders like Fidel Castro and Hugo Chavez.
The ads have been in circulation since Tuesday on Spanish television programming around the state.
The comparison with Castro and Chavez touch a nerve in the Latin American community in Florida, which tend to be militantly opposed to the left-wing leadership in Cuba and Venezuela, said ABC News.
Cubans make up a large bloc of voters in the Miami-area and tend to vote Republican.
The commercial asks "who supports Obama?" and then lines up clips of Hugo Chavez, Venezuela's president.
The ad also features Raul Castro's daughter who says that she'd vote for Obama.
According to CNN, the commercial also mentions an email sent out by the Environmental Protection Agency that had a picture of Che Guevara on it.
The ad appears in the final week of the election campaign, which has seen more aggressive messaging.
The closing clip in the ad shows Chavez saying that Obama would likely vote for him if he was Venezuelan.
