It's not clear who will redraw California's congressional districts in 2011, but it's a near certainty that the Inland Empire will have more seats in Congress once the new lines are in place, experts say.
Thanks to the state's partisan redistricting process, a new Inland Empire seat would likely be Democrat-controlled and would come at the expense of the Bay Area, which has grown much more slowly than San Bernardino and Riverside counties.
"It's probably going to be a regional shift of seats from north to south," said Jack Pitney, a political science professor at Claremont McKenna College.
When new congressional districts were last drawn in 2001, all of California's 53 districts had roughly the same population. But a report from Claremont McKenna's Rose Institute of State and Local Politics shows that most of the Inland Empire's congressional districts are overpopulated while the Bay Area's are underpopulated.
Six Inland Empire districts - including the San Bernardino County districts held by Rep. Joe Baca, D-San Bernardino; Rep. Jerry Lewis, R-Redlands; and Rep. Howard P. "Buck" McKeon, R-Santa Clarita - are among the most overpopulated in California.
The district held by House Speaker Nancy Pelosi, D-San Francisco, and the four districts surrounding it are among the state's most underpopulated.
In 2011, following the 2010 census, the state's congressional districts will be redrawn. Unlike the state's Assembly and Senate districts, which will be redrawn by an independent citizens commission, the congressional districts are set to be redrawn by the Democrat-controlled Legislature.
That means, Johnson said, Democrats will try to maintain or possibly increase the edge held by Democrats in the state's congressional delegation. Out of 53 seats in the state, 34 are held by Democrats and 19 by Republicans.
"There's a pretty good chance the Democrats will collapse a Democratic seat in the Bay area," said Doug Johnson, a scholar with Claremont McKenna College's Rose Institute of State and Local Government. "Then the top priority would be to draw a new Democratic seat somewhere else. That could be in the Inland Empire."
