Although a victory is expected for Mitt Romney here in the primary elections, the other Republican nominees have rallied to shake voters about the possibility of what could happen if they voted contrarian -- to the party: as a result, the campaign had turned much more negative in the final hours before the vote.
Romney supporters in his own party, and Romney himself, characterize his opponent Newt Gingrich as being unreliable, not the conservative he claims to be, and even ridicule him because of his statements about the possibility of a lunar base with U.S. personnel.
Romney scoffed at the idea, saying "A colony on the moon? Frankly, not the kind of great idea that America is looking for."
For his part, Gingrich has been traveling the state describing Romney as a liberal, having previously supported policies related to those of Obama, such as supporting abortion rights and imposing limitations on gun control. Gingrich also accused Romney of being against full religious freedom.
In the final hours before the primary, Gringrich resorted to more desperate rhetoric, going as far as accusing Romney of making Jewish Holocaust survivors eat "non-kosher food" on Medicare.
The population of older Jews in Florida is one of the largest in the country.
It is perhaps because of this negativity that voters remain relatively unenthused about any of the Republican hopefuls.
A survey conducted by the Pew Hispanic Center and released yesterday indicates that 52 percent of registered Republican voters say that the available pool of candidates is "poor." This figure is higher than that found in the same poll a month ago -- 44 percent.
Only 46 percent say the pool of candidates is "good."
In a cafe in Doral, a diverse Latino enclave with a predominantly immigrant population, Saul Hernandez argues with his friend Alberto Flores about Republican candidates. Both are Cubans who arrived a few years ago, and this is the first time either one will vote.
"Honestly, I [registered] Republican because my family, who has been here for years, is. The truth is, I haven't heard anything positive from these candidates. All they do is fling dirt at one another," Hernandez said.
Flores said he'll vote for Romney.
"I think the fact he's an entrepreneur means he'd do well, but who knows," Flores said. "I don't know if I'll eventually vote for him against Obama. I heard the other day that Romney wants to once again halt travel to Cuba. That doesn't seem right to me because I still have family there."
Apart from the duel between Romney and Gingrich, there are at least two other parallel campaigns taking place: the fight for the Latino vote in Florida, which is considered a "swing vote," or deciding vote of 11 percent, and the fight of both nominees against the president.
As far as the Latino line on the vote, Matt Barretto of Latino Decisions, said in a memo published yesterday that, there are no less than "three different votes: foreign-born Cubans, Cuban Americans and other Latinos, mostly Puerto Ricans," and all three hold very different and varied political views.
Puerto Ricans and other voters are mostly registered Democrats and do not participate in these primaries.
Gingrich, who courted immigrants last week here in Miami, yesterday released a new Spanish-language, television campaign ad in which young Cubans suggest that "this country is looking a lot like the country from which our parents fled."
Another way of suggesting what many others have insinuated on numerous occasions -- that President Obama is a radical socialist.
"My family knows what it is like to lose the country you love. It won't happen to us again," said a young woman, while another said the United States resembles Cuba because there is "socialized medicine and taxes that paralyze businesses."
Romney included Puerto Rican Gov. Luis Fortuño in a televised campaign ad in an effort to bolster his image. Fortuño promotes Romney in the ad, and in English, saying "We need a leader who understands that to create jobs we have to cut taxes."
Democrats are also attacking Republicans, but only Mitt Romney.
Congressman Xavier Becerra (D-CA) was on hand in Miami with another representative of the Democratic National Committee attacking Romney for "lining his pockets at the expense of American workers" through transactions as an investor in failing companies.
