Arkansas, Pennsylvania, and Kentucky have gotten all the attention ahead of Tuesday's primaries.
But there is another state going to the polls -- Oregon. There are at least two races of interest.
Former Gov. John Kitzhaber is looking to win election again. He has a primary opponent in Bill Bradbury, an environmental activist, who was endorsed by Howard Dean.
Kitzhaber is the favorite.
The race for the GOP nomination is perhaps the more interesting one to pay attention to. Former professional basketball player Chris Dudley, who played for the Portland Trailblazers, stands tall in fundraising, outraising his opponents.
One robo-poll showed the 7-feet-1-inch former center with a substantial lead (but just shy of his 46% career free-throw shooting percentage). Another survey, though, showed a different story with businessman Allen Alley with a slight edge. Another robo-poll showed Kitzhaber and Dudley in a general-election tie. There hasn't been a lot of -- if any -- reliable polling in the state for this race, so it's tough to read too much into what the state of play actually is.
But if Dudley wins, in this anti-incumbent climate, his name ID and ability to raise money, could at least give Kitzhaber some headaches.
Wyden up for reelection
Incumbent Sen. Ron Wyden is also up for reelection. Wyden was first elected in 1996 and is the clear favorite. He does have two primary opponents on the ballot -- Pavel Goverman and Loren Hooker.
Don't expect Wyden to have a problem here, but some of his opponents' answers to their election guide questionnaires merit mentioning.
Goberman described car insurance as "Street Robbery. If no accident - 50% money back." He also believes "English must be official language" and he claims, "I will make peace on the MiddleEast."
Here's Hooker: "NO NEW SPENDING-I don't care if it's 'paid for'. NO NEW OR INCREASED TAXES-on anybody." And: "TAKE BACK all unspent bailout money. TAKE A CHAINSAW to the Budget. AUDIT THE FEDERAL RESERVE."
The main Republican is law professor Jim Huffman. Wyden is expected to hold double-digit leads for over him.
Oregon is entirely vote-by-mail. Ballots must be returned by 11:00 pm ET (8:00 pm local time).
