Iowa Republican leaders were thrilled to learn this week that active registered Republicans outnumber active registered Democrats in this state for the first time since 2006. The Secretary of State’s office is working with county auditors on voter list maintenance. Voters whose addresses cannot be confirmed are being moved off the active lists, and in many counties, more Democrats than Republicans are being shifted to “inactive” status. Inactive voters are still eligible to vote in Iowa, but they must show ID at the polling station in order to vote on election day.
The Republican voter registration edge is likely to grow, because there are many more competitive GOP than Democratic primaries for the Iowa House and Senate. Republicans also have competitive primaries in two of the four Congressional districts, whereas Democrats have two candidates only in IA-02. On June 5, a significant number of Democrats and no-party voters will switch to the GOP in order to vote in a primary.
After the jump I’ve posted updated active voter registration numbers for Democrats, Republicans, and no-party voters in all 99 Iowa counties, grouped by Congressional district. The data come from this page on the Iowa Secretary of State website (pdf), except that I placed Wayne County in IA-02 where it belongs, rather than in IA-03. (UPDATE: That error has been corrected on the official site.) In some counties, the numbers are barely changed from last month’s figures. Other county auditors have taken many more people off the active voter rolls.
