Likely Dem pickups

Likely GOP pickups
Georgia
Tossups
South Carolina, North Carolina, Florida, Louisiana, Oklahoma, Pennsylvania and South Dakota.
I include South Dakota because of the polling showing Daschle with only a small lead, although I expect him to win. If Beasly and Coburn win their primaries, I give the GOP an edge in South Carolina and Oklahoma. Assuming Betty Castor wins, I give the Dems the edge in Florida. Louisiana probably won't be decided on election day, but based on what happened there the last two statewide elections, I give the Dem the edge. North Carolina is a true tossup. Pennsylvania is a wild card. I really think Toomey will pull the upset, which would give the edge to Hoeffel. If Specter wins, he will have an edge, but can be beaten.
Bottom line prediction as of St. Patrick's Day, a one seat Dem gain with the balance of power lying in North Carolina and Pennsylvania.
