The Ron Wyden Oregon Senate campaign in 2004 didn't talk a lot about the opposition (which was slight), but it's talking a little more this time. And it's even made an accusation of the opposition, which on its face looks pretty sound.
Jim Huffman is a stronger candidate, but yes, he seems - certainly at this point - nowhere close to Wyden in numbers, either money or polling percentages. The Wyden line: “Huffman and Moore are releasing laughable poll numbers to distract reporters from their as-yet unreleased fundraising numbers due out today.”
Moore being pollster Bob Moore, who released numbers showing Huffman ahead. Which might not be a cred-blaster except for the strong of other polls giving Wyden a big lead, and an apparent dispute about whether Moore is polling for Huffman. (The Wyden people supply some evidence that he is.)
The whole statement is worth reading.
