Johnson County Primary: Party Change Numbers

Iowa Starting Line took a look at party registrations in the just finished primary election.

‏Here in Johnson County, the Democrats are up 2132 active registrations through the end of June. The peak was even higher but invariably we see some double switchers every primary.

By percentage, Dems jumped from 45.69% on May 4, the Friday before voting started, to a peak of 48.32% on June 14 when voter history was updated. That's just short of the all time Johnson County Democratic peak of 49.26% after the 2016 caucus and primary cycle. Double-switches and new registrations have dropped the Democrat's share to 48.15% as of Thursday June 18.

When there's not a caucus or primary going on, new registrations, especially from the Department of Transportation, tend to default to No Party. I cannot remember the last time I saw a registration come through from the DOT changing from No Party to a party, any party. DOT changes are ALWAYS the other way around - from parties to No Party.

Republican registration in Johnson slipped from 20.17% just before primary voting started to 19.79% after primary, and even with double switching has continued to drop slightly.  (Most primary double switchers in Johnson were No Party to Democrat to No Party, rather than R to D to R.)

Also, a pet peeve: The Secretary of State's stats including the statistical category "Other" - when there is only one thing in "Other," the Greens.
