Here is a possible scenario for redistricting in Oregon. I followed county lines and geographical areas as close as possible and something like this could actually pass the legislature.
CD1: PVI of D+4 – David Wu ultimately could have gone down in this configuration or barley squeaked by, if not in 2012 due to current events. I took out all of Multnomah County and added Tillamook County, which went for Dudley in the 2010 gubernatorial election. Dudley would have won this district by a small margin.
CD2: PVI of R+8 – This district is perfect for Greg Walden, it is a few points less Republican than before as the district includes east Lane County and Springfield. A tea partier might struggle if Walden decides to retire but this is still a solid GOP district for years to come.
CD3: PVI of D+26 – This district is even more Democratic than before and contains only Multnomah County and parts of liberal Clackamas County (Gladstone, Milwaukie). There should be no shortage of electing Democrats in the future.
CD4: PVI of EVEN – The district is a true swing district as I have eliminated Springfield and east Lane County from the district and added Jackson County and the the entire Benton County to it. As it stands Peter DeFazio would have to run against Greg Walden, but he could easily move to Eugene. Art Robinson would have possibly won in 2010 but would be in trouble in 2012 if it is a strong Dem year. A moderate like Rick Dancer would be win election after election if he chose to run.
CD5: PVI of R+2 – This district includes the entire Clackamas County except with the poor parts of Gladstone and Milwaukie, but also includes a more liberal Lincoln County on the coast. Scott Bruun would have won against Kurt Schrader in 2010, and is no longer considered a swing district.
