The internals of the IBD/TIPP poll:

The June 1-8 poll of 912 U.S. adults, including 841 registered voters

Democrat(34%), Republican (29%), Independent/Other(32%), Not sure/Refused(5%).

The internals show it's the most worthless of polls because it's not likely voters. It's not even registered voters. It's just voters of whom some are registered voters. And it's skewed towards Democrat voters. Rasmussen is always likely voters which makes it a more valuable tool for probable end results.

Huh.   IBD usually does better than that but (evidently) not always.

Exactly.. Ras is far more accurate, and the party affiliation of RePubs +2 over Dems.
