Earlier today, Salon's Walter Shapiro wrote that Indiana's 9th District might be the "first barometer" of tonight's results. What we're seeing there right now: With 28 percent of the precincts reporting, Democrat Baron Hill holds a small lead over Republican incumbent Mike Sodrel. At the moment, at least, Democrats hold substantial leads in two other Republican-controlled Indiana congressional districts; indeed, CNN has just projected that Democrat Brad Ellsworth will beat Rep. John Hostettler in the Democrats' first pickup of the night. As Shapiro wrote, it will be a long night for Karl Rove and the GOP if the Democrats hold on to go three-for-three in Indiana.
The night may seem like an eternity if Democrats can pick up any seats from Republicans in Kentucky, too. At the moment, Democrat John Yarmuth is leading Republican incumbent Anne Northup, albeit barely.
