St. Petersburg, Florida -- Gas prices are expected to be a hot button issue this campaign season.
But how do you know if candidates are making promises they can keep?
The head of the Republican Party of Florida says President Barack Obama has broken a promise, but is that true?
We teamed up with PolitiFact Florida to look at the facts.
What you pay at the pump is expected to be what the candidates talk about in campaign 2012.
Lenny Curry, head of the Republican Party of Florida, says the hot topic will make it difficult for President Barack Obama to win Florida. Curry says Obama promised gas prices at $2.50 a gallon.
PolitiFact Florida tracks all of President Obama's campaign promise on the Obameter.
"We went through there and we found no instance of promising for 2.50 a gallon gasoline," says Aaron Sharockman with PolitiFact Florida.
Sharockman says they contacted the Republican Party of Florida for evidence, but didn't hear back. "It's always an interesting sign for us because it means there might be something here that maybe this quote isn't as accurate as it seems."
So fact checkers combed through the president's speeches, "Only thing we found is he talked about some trying to make renewable energy more feasible and increase the production of renewable energy across the country and he thought that would lower gas prices, he never promised a specific number though," says Sharockman."
But there is a presidential candidate who has promised 2.50 a gallon.
"Honestly, we don't know where he got the figure from, we can speculate that maybe he got confused with Newt Gingrich's policy, but that's just speculation," says Sharockman.
So how difficult is it to promise a specific price you pay at the pump? Sharockman says experts are very skeptical the president could have such a specific influence.
"The president has some leeway to do things that could influence gas prices, whether it's tapping into some of our reserves, potentially if you drill for more oil offshore or onshore, that could lead to lower gas prices, in the future."
And President Obama has discussed the need to be energy independent though reduced consumption and renewable energy sources, but he has not promised $2.50 a gallon, so PolitiFact Florida rates Curry's statement: FALSE.
Because getting too specific about gas prices can be dangerous, experts say it's likely you'll see more nuance claims about how Obama promised to lower gas prices and prices are headed to four dollars a gallon.
