Mitt Romney hit a new high for support among Florida likely voters, a new Rasmussen poll shows, as Romney built a four-point lead over President Obama.

“This is the widest gap between the candidates in surveys this year,” Rasmussen Reports announced today in a statement on the poll, which showed Romney leading Obama in Florida 51-47. Rasmussen’s survey shows that voters trust Romney more on both the economy (51-45) and national security (51-47). The poll has a four-point margin of error.

Last week, Rasmussen only had Romney leading 49-47 in Florida.
