Oregon Sen. Ron Wyden is back below the dreaded 50% mark in a new Rasmussen poll (June 17, 500 LV, MoE +/- 4.5%) but continues to lead Republican Jim Huffman by double digits. Huffman, a law professor, is still unknown to much of the state, and four-in-10 voters still don't have an opinion of him one way or the other. As for Wyden, who's finishing up his second full term in office, 52% hold a favorable opinion of him. Still, even in this Democratic-leaning state, he's below 50%.

Wyden 47 (-4 vs. last poll, May 24)
Huffman 37 (-1)
Und 10 (+3)

RCP rates this race Likely Democrat.
