I hope Wenzel Strategies is right here but if I were a democrat being polled I would say anything that helps keep him in the race.
I looked up Wenzel Strategies and saw where they claimed 20% of GOP voters would vote for zerobama. That doesn’t seem quite right.
Moderates supports McCaskill 63-22, yet Very Liberal supports her only 58-34? That is not possible unless the type of shenanigans you’re alluding to is happening, or something else weird happening in their sampling. I’m very skeptical of this poll.
