registrations can be how people registered during the carter years or before.
my mom was registered for 20 years as a Democrat while she was voting republican... if you asked her, she would identify herself as republican.
and note..
In Florida , as of last month there are 4,627,929 registered Democrats and 4,173,177 registered Republicans, which amounts to a a 454,752-voter advantage for Democrats. (Keep in mind, Florida has 11.5 million registered voters, so there are a lot of unaffiliated and third-party voters.)
In 2008, there were 4,800,890 registered Democrats in Florida and only 4,106,743 registered Republicans, a 694,147-voter advantage. So while the number of voters who registered with the GOP is up from four years ago, Democrats are down roughly 170,000.

so when you combine the fact that dems are losing voters on the rolls and dems have lost hundreds of thousands of self identified voters you can see when your D plus 9 polls are total bullshit.
I would say on the voter rolls alone consider that Rs are more likely to vote by about 3 %... you should at best have a completely balanced poll.
If you look at voter trends... you have to go R plus 3 or more.
Quote from AK Forty Seven:
It was D + 4 in Jan.After Mitts last few months it is likely higher now

Figures released by the Division of Elections today show Florida has 11.2 million voters, with 40.5 percent registered as Democrats and about 36.2 percent as Republicans. The gap of 4.3 percentage points between Democratic and Republican registrations compares to a 5.8-point gap that favored Democrats heading into the 2008 presidential election.
