Conway - Paul Race Dead Heat

In the Kentucky Senate race, Rand Paul has been enjoyng a significant lead over Democrat and state Attorney General Jack Conway.  That appears to be changing fast.  In the just-released Courier Journal/WHAS11 Bluegrass Poll, Paul leads Conway 49 to 47%, which is within the margin of error. The previous poll, released the first week of September, gave Paul a lead of 55 to 40%.  The results indicate that Conway has moved well ahead among women while Paul still leads among men. 

Is Tea Party strength weakening?  Perhaps November won't be the Republican blow-out the press has been endlessly predicting?  This is just one poll, but it's interesting.
