This IS PPP and its very early on, PPP always overestimates democrats in polls when its not at least a half year away.
This is a bad talking point that needs to stop. I was hoping only Oldies bought into this stuff.
But it's true. I remember last summer, most of the polls had Obama leading Romney by only a few points like states in Colorado and Virginia, but PPP had him leading there by almost double digits. And besides, what makes you think that a Democratic pollster wouldn't have results that are biased toward Democrats? They may be accurate just before an election, but their early campaign polling is awful.
