So, real polls show Crist in the lead, and garbage polls show Scott in the lead. And this race is characterized as a tossup?
I can see these political forecasting meetings now:
"Well, the pros are showing that Charlie Crist is going to defeat Scott, but the idiots who don't know what they're doing are all showing a Rick Scott lead--I don't know who to believe!"
The race is a tossup because the majority of the polling has the race with either a tie or slight Crist lead. It's worth noting that this particular poll was for a left-leaning group.
At the end of the day, the race slightly leans Crist, but he doesn't really have a persistent lead outside of the margin of error to call it anything other than a tossup.
The reliable pollsters are all in consensus that Crist has a small lead. Just because his lead is small, it doesn't mean it doesn't exist.
