Updated voter registration numbers in Iowa's Congressional districts

For the third month in a row, registered Republicans in Iowa slightly outnumber registered Democrats. The latest figures from the Iowa Secretary of State's office (pdf) show 663,969 active no-party voters statewide, 607,936 active Republicans, and 595,423 active Democrats. After the jump I've posted the latest active voter registration numbers in all 99 Iowa counties, grouped by Congressional district. The most evenly-split county is Decatur in south-central Iowa, with 1,749 registered Democrats, 1,783 Republicans, and 1,775 no-party voters as of June 1.

Any comments about the 2012 elections in Iowa are welcome in this thread. The deadline to enter Bleeding Heartland's 2012 Iowa primary election prediction contest is Tuesday, June 5, at 7 am.

  • 4 of 5 incumbents favored

    The numbers look good for the incumbents in districts 1, 2, and 4. In district 3, Latham has an advantage over Boswell. In district 4, I hope voters feel Steve King has gone so far to the right that he looses independents and some Republicans, but that's probably wishful thinking.

  • IA-03: Des Moines metro area

    The Des Moines metro area officially includes Polk, Dallas, Guthrie, Warren, and Madison Counties according to the US Census Bureau. Those counties account for the lion's share of the district's population. Here's the precise (and unsurprising) breakdown based on the registration numbers:

    81% of the district's Democrats live in the Des Moines metro area.

    70% of the district's Republicans live in the Des Moines metro area.

    73% of the district's no-party voters live in the Des Moines metro area.

    When you take out the other counties and just leave Polk, you see while Dems are more dependent on the urban county, it's quite important for Republicans and no parties too:

    64% of the district's Dems live in Polk County.

    50% of the district's Republicans live in Polk County.

    50% of the district's no party voters live in Polk County.

    My point? Looking past Boswell and Latham to future races in this district, it'd be nice for the Des Moines area to be represented by someone actually from the Des Moines area, given its importance in the district for all parties.
