Pearce: A brand new poll shows Senator Elizabeth Dole regaining a solid lead after being down to her challenger Kay Hagan following an onslaught of negative advertising by the DSCC. It was also a great day for the top of the ballot in NC as John McCain jumped from a 3 to a 20 point lead over Barack Obama in the state. Elsewhere around the country, McCain continues to enjoy a surge following his pick of Palin and a convention that clearly grabbed the attention of the electorate. He has taken a 15 point lead among independents and gained in the key battleground states of Florida, Ohio, Pennsylvania, Virginia, Michigan, New Hampshire, Missouri, Montana and Wisconsin. This has been a stellar week for Republicans as excitement for the historic presidential ticket trickles down, but will it last? We could be seeing the major turning point in the 2008 election cycle.
