Voter Registration Maps: Party Growth, 2017 to 2018

Continuing my Voter Registration Maps series update, here are maps representing the changes in percentage by county of Republicans, Democrats, and Independents. The state election board appears to have done a purge of the voter rolls, so changes are not as substantial as they have been the last few years, with a much more consistent pattern across the state.

As with last year, Republicans made positive gains in all 77 counties. The smallest growth was in Canadian County (+0.3%) while the greatest was in Jefferson County (+3.27%).

Once again, Democrats posted losses in every county. The smallest loss was in Cleveland County (-0.7%) while the greatest was in Jefferson County (-3.17%).

Independents had a down year, relatively speaking, losing percentages in 23 counties - by far a record for recent years. Texas County had the greatest loss at -0.997%, while Ottawa County once again had the greatest growth at 1.22%.
