Advertising is having a huge effect in the Senate race.
With Democratic candidate Kay Hagan on the air during the May primary, her numbers improved against U.S. Sen. Elizabeth Dole.
Dole then got a bump from her own ads, but another round of ads attacking Dole has narrowed the gap again. The entrance of Libertarian Chris Cole to the race also complicated things.
Here are the numbers:
May 8-9: Dole 48, Hagan 43
May 14-17: Dole 45, Hagan 43
May 17-19: Dole 50, Hagan 46
May 28-29: Dole 47, Hagan 39
June 10: Dole 53, Hagan 39
June 18: Dole 48, Hagan 38
June 26-29: Dole 51, Hagan 37
July 12-14: Dole 54, Hagan 42
July 15: Dole 54, Hagan 43
July 14-16: Dole 47, Hagan 38, Cole 2
July 23-27: Dole 49, Hagan 40, Cole 4
July 28-30: Dole 50, Hagan 42
Aug. 9-11: Dole 46, Hagan 41, Cole 7
In all of the polls, Dole is ahead, but her lead ranges from as high as 14 points in June to as low as two points in mid May. The recent tightening shows this could be a volatile race.





Re: Ads make a difference in Senate race
Not really. While there is definitely a collection of hard core Libertarian voters, in polls, people who respond for the Libertarian are generally dissatisfied Republicans lodging a protest vote.
Almost all of them will come back around and vote R. Especially if the race is close.
