35 percent?

A recent Quinnipiac University poll suggests that Bush would lead Hillary Clinton by approximately 7 percentage points if the election were held last week. What I find odd is that only 35 percent of the people polled were Democrats (372 out of 1055 registered voters). Is that the actual Democratic representation in the voting pool? Are there really 30 percent of people who aren't registered?

And, more importantly, why are so many people still believing Bush's hypocritical nonsense after all this time that he can still beat Democrats by 7 to 15 percentage points?
