In Florida, the election for governor is heating up.
Gov. Jeb Bush and Democratic challenger Bill McBride took part in a one-hour radio debate.
A final televised debate is scheduled next week in Orlando.
A new Zogby Poll shows Bush with the support of 48 percent of voters, while McBride has 45 percent.
Seven percent of the 500 likely voters surveyed were undecided. The survey has a margin of error of 4.5 percentage points, which places the race in a "statistical" dead heat.
