There are two million Hispanic voters in Florida. It's a constituency that has the power to shift a tight election, so both political parties have tried to sway the Hispanic vote their way.

President Barack Obama has held a comfortable lead with Hispanics. But now there has been a significant shift in the polls.

An exclusive Tampa Bay Times/Bay News 9 statewide poll shows many Hispanic voters dropping their support for Obama.

Last month, 52 percent of Hispanic voters polled said they would vote for the president. That has now dropped to 44 percent.

Romney picked up some ground among Hispanics, from 43 percent to 46 percent. And the number of undecided Hispanic voters has doubled from 5 to 10 percent.

"The Hispanic community is sophisticated enough to see that Romney is not their enemy," Florida Decides Republican analyst Chris Ingram said. "He's not calling for rounding up 14 million voters by sending them back to their country of origin. He's a guy that recognizes that Hispanics, even illegal immigrants, have a role to play. He has compassion and, moving forward, isn't going to penalize people unfairly."

The president scored major points with Hispanics in June by temporarily stopping the deportation of most young people who are in the country illegally - the so-called dreamers.

Obama, according to Florida Decides Democratic political analyst Ana Cruz, needs to remind Hispanics he is their president.

"It's going to be incumbent upon the president in these two next debates to perform well and really remind folks of the work that he has done," Cruz said.

In the first debate, immigration was no mentioned. No doubt, Hispanic voters will be listening for that topic to come up in the next debate. However, the majority of Hispanic voters say the economy is their No. 1 concern.
