  • What's the reason?

    Are more Democrats leaving to the non-affiliated category? Are Republicans just doing a better job getting new voters? I’m moving to Iowa in a few days so next month you’ll get at least one more Democrat.

    • they are cleaning up the voter rolls

      If you compare the county numbers to those from February, you’ll see that there are fewer active registered voters in all categories. Democrats have lost a bit more than Republicans during that process.

      Earlier this year, lots of Democrats and no-party voters registered as Republicans to participate in the Iowa caucuses. I expect more of that in June, because there are a lot more competitive GOP primaries around the state than Democratic primaries.

      Welcome to Iowa!

  • thanks

    thanks for the reminder! i need to switch back to Dem.  had to give the Republican caucuses a try once….and once was enough
