Jim Geraghty points out a possible issue with PPP’s polling in Kentucky: PPP has Democrats taking a greater share of the 2010 electorate than the exit polls gave them in 2008.
That strikes me as most unlikely. Democrats were remarkably motivated in 2008, but it is Republicans who enjoy that status today. So I’m inclined to discount PPP’s result of a tie in Kentucky.
