I don't think any poll is joke, I think both polls are well within the margin of error and I think it is going to be a contested race. What is a joke poll was that ARG poll that showed Hodes leading well outside the margin of error 15 pts over Sununu. I think Sununu will have his hands full, he isn't the concillater, reaching across the aisle like Gregg did, all he is known for is his independence on ANWR. Gregg has done more than that to vote against ANWR drilling in reaching across the aisle.
Polls aren't jokes because they're outside the margin of error; they're jokes when nothing reasonable can be discerned from the results - which is certainly the case when there are more undecideds than anything else.
