How can we trust any Hawaii polls given that it's near-impossible to poll with any accuracy? I certainly don't believe that Case would outperform Hirono. Nor do I understand the Case hate- he's only slightly less liberal than Hirono. The difference is that he's an anti-machinist and Hirono is an Inouyebot.
The anti-Case people are probably more upset at the way he's obsessed with running for and remaining in office and his boneheaded primary challenge, but I agree supporting Lingle over him is absurd.
