CNN: Casey-McCormick Tied
The CNN news organization released the results of their series of key statewide polls yesterday, and the most interesting result is a 46-46% tie between Pennsylvania Democratic US Senator Bob Casey, Jr. and Republican businessman David McCormick (8/23-29; part of a six state polling series; 777 PA likely voters; multiple sampling techniques). This is the first time the two have been on equal footing.
