Public Policy Polling has looked at a trend in their recent results - Republican candidates winning among Independents in 25 of 33 statewide contests they've polled since early June.

No spinning. That's bad for Democrats. The more Republicans lead among independents, then the more likely Republican turnout will be higher than Democratic turnout come election time. That usually results in Republican wins.
