Polimetix is one of the worst online panel 'surveys.'
It consistently tilts far to the left.

These were the final YouGov polls in 2010 and they sometimes overestimated the Republicans and sometimes the Democrats.
Sometimes they even had good results like in the CO Senate race, a race that every other pollster got wrong.
In 2008, they were much better though.
TB,
You are beginning to sound like Ernest ("you cannot say that")
Well, I can and did, with good reason.
You really should investigate who was one of the founders of the 'poll,' and has totally disassociated himself from it.
Also, you really should look at their total record. Its simply awful.
