This over polling of Democrats vs. Republicans has a reason but is based on what determinants exactly, besides the obvious count of likely voters are largely Dems? Are there other more obscure factors, I wonder?
They are using turnout models from 2008 when dems were +7, in 2010 the pubs and dems were even.
This year IMO the turnout model will be even to R+2, Rasmussen has had the Generic ballot R+3 for awhile though the latest take was R +1,
When you factor in the enthusiasm gap...
The polls are trying to bump up barry the bozo.
