The U.S. Census Bureau confirmed this week that Iowa will lose a Congressional district following the 2010 census unless we experience unprecedented (for Iowa) population growth in the next two years:
During the past eight years, Iowa has gained as many people - about 76,000 - as states like South Carolina and Virginia gained between 2007 and 2008 alone.
To retain the congressional seat, the state would have to gain nearly twice that number by 2010, according to projections by Election Data Services, a Washington, D.C.-based consulting firm that analyzes the impact of demographics on politics.
So, Iowa will be left with four Congressional districts. No one knows what the new map will look like, but it's likely that the 2012 race in the new third district will determine whether Iowa Democrats (who now hold a 3-2 edge in U.S. House seats) gain a 3-1 advantage or have to settle for a 2-2 split.

Note: A non-partisan commission draws up the new Congressional map after each census in Iowa, so Democratic gerrymanders will not take place, even if Governor Chet Culver wins re-election in 2010 and Democrats hold their majorities in the state House and Senate.
However, if the Democrats maintain control of the legislature, they have the option of rejecting the first and/or second map produced by the non-partisan commission. Republicans in the Iowa legislature rejected the first map proposed after the last census.
Most of what's now the fifth district, represented by Republican incumbent Steve "10 Worst" King, is likely to become the new fourth district. It makes no difference whether the new counties added to IA-04 come from the current third or fourth districts--that is going to be a safe Republican seat.
Given the voting trends in eastern Iowa, I assume the new first and second Congressional districts will still be relatively safe for Democrats. (Remember, fewer than 10 Republicans in the whole country represent districts with any kind of Democratic partisan lean.) Either Bruce Braley or Dave Loebsack may need to move if the new map throws Waterloo (Black Hawk County) in the same district as Mount Vernon (Linn County), but that should not present much of a problem.
The big question mark is what happens to IA-03. Polk County will remain the largest county in the district, but it won't be as dominant in the new district as it is now. A majority of the votes in the current third district come from the county containing Des Moines and most of its suburbs.
In which direction will IA-03 expand? If the counties added to it come mostly from the southwest, Republicans will have a better chance of winning the district. One reason Greg Ganske beat longtime incumbent Neal Smith in the 1994 landslide was that Smith's fourth district had lost Story and Jasper counties, and gained a lot of southwestern Iowa counties, following the 1990 census.
If IA-03 includes more counties from the southeast, Democrats would be better positioned to hold the seat, although it's worth remembering that Ottumwa resident Mariannette Miller-Meeks carried seven southern counties in her unsuccessful challenge to Loebsack in IA-02 this year.
Speaking at an Iowa Politics forum in Des Moines last month, Miller-Meeks said she was leaving her ophthalmology practice at the end of 2008. She strongly suggested that she will run for office again. Whether that means another bid for Congress or a run for the state legislature was unclear.
