Grand Rapids is in West Michigan, which is traditionally conservatve and Republican. The GR area, however, is becoming progressively liberal, so while the Press endorsement of GWB isn't surprising, newspaper endorsements from the GR area may be changing with the demographics.
The only section in the Greater Grand Rapids area that votes in any Democrats is the NW side of the city of GR. I am in a SE suburb. SE, SW, and NE all usually vote for Republicans. My State Senator is my former mayor, Bill Hardiman.
The Holland and Muskegon areas, which are represented by U.S. Rep. Pete Hoekstra (R-Holland) also usually vote Republican.
