Yeah, it is.
"...1,582 registered voters... 1,067 likely voters"
The party break down in this poll is 45 Dem 31 Rep, a difference of 14 points.
While that is the party breakdown in California in 2008,
in the last 2 mid-term elections, the party breakdown was a difference of 9.4 in 2002, and 8.2 in 2006.
I seriously doubt the party breakdown this year will be any worse than a +8 or +9 for the Dems.
That means this poll gave the Democrats about 5-6 points more than they should.
Adjust it and you have Boxer/Fiorina in a tie and Whitman right there with Jerry Brown.
