Both races are a coin flip. These races are just about dead even and have very few “undecided” voters, so the outcome will hinge completely on turnout.

The challenge is slightly easier for the GOP only because the Democrats have to win both seats to gain Senate control, so the Republicans can hold on if they win either one. For example, they could write off Loeffler, take all the national/outside money they were planning to spend on her, and put it behind Perdue instead. The Democrats have no similar option. They need both.
