ORLANDO, Fla. -

Another day, another poll showing Mitt Romney losing a key battleground state to President Barack Obama.

And some in the GOP have had enough, blasting polls that show Romney getting creamed by claiming the poll samples are biased against Republicans.

The latest attack came after a poll conducted by CBS News, the New York Times and Quinnipiac University gave Obama a nine point lead in Florida.

The campaign manager for U.S. Senate challenger Connie Mack IV -- who the poll showed is losing to incumbent Sen. Bill Nelson by 14 points -- says the polls are "based on highly questionable party identification models that can serve no other purpose than to attempt to sway public opinion and voter enthusiasm."

But Local 6 examined the Quinnipiac poll and found 36 percent of those surveyed said they were Republicans -- which is identical to the proportion of all Florida voters registered as Republicans, 36 percent. (Mack's campaign claimed 27 percent of the sample were Republicans, but that number refers to those who "consider" themselves Republicans, not their actual party registration.)

Forty-three percent of those polled said they were registered Democrats, which is three points greater than the 40 percent that Democrats comprise of the voting rolls.

Third-party and no-party affiliated voters made up only 21 percent of those polled, but comprise 24 percent of the electorate.

The Quinnipiac poll result is not weighted by party affiliation or altered in any way based on predicted voter turnout, so Election Day turnout will be a key factor.

The survey of 1,196 likely Florida voters was conducted Sept. 18-24.
