Just one seat away from a tie, the Oregon Senate should not be forgotten as this year's campaign wrangling gets underway.

So, in a chamber held by Democrats on a narrow 16-14 margin, what do history and the stats tell us?
History hasn't shown many partisan turnovers in recent cycles. There have been some big-turnover cycles, like 1994 (five seats to the Republicans, who took over)or 1958 (four to the Democrats, who took over), they've been sparse through most of Oregon history.
In the last decade, just four Senate seats switched sides. Two of those happened in 2010, both moving Republican: District 26 and District 26, both centered in Clackamas/Multnomah country. The other two were in 2004 which then each moved from Republican to Democratic. One was a mid-term election following the resignation of Republican Lenn Hannon, who was replaced by Democrat Alan Bates. The other, in District 5, was won by Democrat Joanne Verger, who after two terms is retiring from the Senate this year.
Of the Senate seats up for election this year, that District 5 seat in 2004 saw the closest election within the last decade: Verger then defeated Republican Al Pearn by just 1.44%. That and her retirement (and the fact that Republicans didn't contest the seat at all in 2008) put it on the map as a seat to watch. Still, Democrats have a strong veter registration edge in 5 (by 41.52% to 31.57%), and their candidate is the current House co-speaker, Arnie Roblan, who has held the more competitive part of the district since 2004.
