It’s been mentioned on this site that Gary Black won 142 of Georgia’s 159 counties. While that sounds significant, this graphic, much like the county-by-county map of the 2000 presidential election, makes the difference appear even more overwhelming. On the map seen here, the green areas are counties won by Black; the white areas are counties won by any of the other three candidates (Kemp, Greer, or Strickland).
Disclaimer: While winning 89.3% of GA counties is significant, the important numbers are 42.3% and 26.8% (the percentage of the vote Black and Kemp received). Kemp still has a lot of work to do, but endorsements by Greer and Strickland cannot hurt, and 15.5% of the vote is a lot less to make up than almost 90%.
