Two candidates you’ve never heard of until just a few months ago are leading their respective primaries for governor and U.S. Senate, according to the new Quinnipiac University Poll.

Rick Scott, the former Columbia/HCA CEO, has a 43 percent to 32 percent lead over Florida Attorney General Bill McCollum.

That’s just about the same as it was in June’s Q-Poll.

About one in four likely Republican voters polled is still undecided, and 43 percent said they might change their mind before the Aug. 24 primary.

Scott has been blasting the state with millions of dollars of TV ads, all paid for with his own money. McCollum has had to respond with his own ads. 

Those ads have not only helped Scott come out of nowhere to lead the primary race, but they have also had an effect on the unfavorable ratings of both candidates.

Scott has maintained his favorable ratings from June -- 40 percent then, 39 percent now -- but his unfavorable ratings have gone from 12 percent to 26 percent.

The situation is worse for McCollum. Not only has his unfavorable jumped from 19 to 34 percent, but his favorable has dropped from 41 to 34 percent. As you can see, his favorable and unfavorable are now at the same, 34 percent figure.

On the Democratic side, billionaire Jeff Greene has moved ahead of Rep. Kendrick Meek. It is now Greene 33 percent, Meek 23 percent.

Meek had a two-point, 29–27 lead over Greene in Quinnipiac’s June poll.

But the situation here, like the Republican governor’s race poll, is apparently still fluid. Of the Democrats polled, 54 perecent said they might change their mind before Aug. 24.
