Maps: see where the GOP and Dems are overperforming in Oklahoma Early Voting

The Oklahoma State Election Board has been releasing data on the early voting turnout by day, with Saturday set to be the final day for early voting to take place. I took a look at the statistics, and put together these two maps to show what's currently going on.

This first map compares the voter registration leader in each county to the proportion of voters by party who have voted early thus far. A blue county means a higher percentage of Democrats have voted than are registered in that county, and vice-versa for red counties. 

Example A: as of January 2020, Adair County had 47.46% Democratic and 40.26% Republican. As of 5pm Friday, 46.38% of Adair County early voters were Republicans and 41.85% were Democrats. Adair County goes on the map as red due to a higher proportion of Republicans casting early votes than are registered.  

Example B: as of January 2020, Caddo County was 47.52% Democratic and 38.47% Republican. As of 5pm Friday, 53.16% of Adair County early voters were Democrats and 40.36% were Republicans. Adair County goes on the map as blue due to a higher proportion of Democrats casting early votes than are registered. 

Now for the map:

This next map looks at which counties have "flipped" so far in early voting.

Example A: as of January 2020, Johnson County was 51.13% Democratic and 35.95% Republican. As of 5pm Friday, 37.18% of Johnson County early voters were Democrats and 54.4% were Republicans. Atoka County is a registered Democrat-majority county with more Republicans voting early thus far than Democrats.

Example B: as of January 2020, Cleveland County was 47.9% Republican and 33.18% Democratic. As of 5pm Friday, 44.03% of Cleveland County early voters were Democrats and 41.79% were Republicans. Cleveland County is a registered Republican-plurality county with more Democrats voting early thus far than Republicans.
