The latest Zogby poll — a big one with a very low margin of error (±1%) — has troubling numbers for Senator Hillary Clinton.
She's dropped below all five top Republicans in prospective head-to-head matchups:
Giuliani 43 / Clinton 40
Romney 43 / Clinton 40
Huckabee 44 / Clinton 39
Thompson 44 / Clinton 40
McCain 42 / Clinton 38
The news is somewhat better for Edwards, who is running neck-and-neck with the GOP frontrunners.
Obama, meanwhile, is seen cleaning Republican clock, beating each opponent by at least 5 and more often 7 percent.
This if these numbers keep up they'll put a major dent in Clinton's electability cred. They certainly gird Obama's argument that he's the one Democrat who can attract open-minded independents and Republicans.
