Some Senate seats I'll worry about all the way to November, but today when I looked at the list of new polls out, I got a flood of races I'm pretty comfortable calling for the Republican, barring any new news of course.
Georgia: Johnny Isakson +12 over Michael Thurmond per Insider Advantage for WSB. MoE 4.
Louisiana: David Vitter +12 over Charlie Melancon per Clarus Research Group for WWL and other Louisiana stations. MoE 4.
Arkansas: John Boozman +38 over Blanche Lincoln per Rasmussen Reports. MoE 4.
Some may worry over these races when one of the Republicans makes a brief but inevitable dip or one of the Democrats makes a brief but inevitable rise in the polls. However I might not even write about any of these three races anymore unless I hear of a reason they should be changing, or see sustained movement toward the Democrats.
