Driven by polarization around President Trump, the 2018 elections will see dozens of battleground races across the South. The Cook Political Report, for example, projects that four U.S. Senate races in the South, 21 U.S. House contests, and elections for governor in Florida and Georgia are all close and could be decided by razor-thin margins.

While polls over the summer had shown Democrats to be highly motivated for the 2018 mid-term elections and preparing for a major "blue wave" of Democratic voters, more recent surveys suggest that Republican voters are now equally interested in the November contests, almost erasing the Democrats' enthusiasm advantage.
