43% Scott (R)
41% Crist (D)
4% Wylie (L)
The survey of 625 likely voters was conducted Sept. 2-4, and Mason-Dixon cautioned that its sample reflects current voter registration in Florida (41 percent Democrat, 37 percent Republican, 21 percent other), and "does not assume a higher or lower turnout by either political party." Considering the Republican turnout is consistently at least 4 percentage points higher than Democrats in off-year elections, it's reasonable to assume Scott would have a higher lead if the sample reflected the likely voter turnout.
