This story is idiotic. Even the smallest amount of research would allow the writers to know that the Hispanics in Florida are mostly Cubans not Mexicans. All this open borders crap is irrelevant. Here is what is relevant: what has Romney said about how he wants to handle Cuba? McCain has been concrete and has vocally pushed for prosecution against Raul Castro for the 1996 shootdown of the Hermanos al Rescate planes which resonates very strongly with Cuban exiles. Romney just gives generalities. McCain has been supporting Cuban exiles in Congress for years. Romney just discovered them this year when he had to run for election in Florida and then decided to group them into a comprehensive Latin American Policy Group (basically equating their legitimate struggles against communism with those of illegal Mexicans in the country).
Conservative Hispanics in Florida voted for McCain because the Romney campaign completely ignored them. Romney could have won them if he would have paid attention. He didn’t and lost.
I think that amnesty Mel Martinez’s endorsement helped too.
