In the three-way Democratic primary, former State Representative Peggy Lamm  had the highest favorability rating (24 percent) but also the highest unfavorability rating (19 percent). Twenty-nine percent were neutral on her candidacy. Lamm's rating of 28 percent who were unfamiliar with her was the lowest of the three Democrats. Those polled gave former State Senator Ed Perlmutter  a 12 percent favorable rating, 15 percent unfavorable, 31 percent were neutral and 42 percent were unfamiliar. Attorney Herb Rubenstein  received a 4 percent favorable rating, 11 percent unfavorable, 29 percent neutral and 56 percent did not know him.Peggy Lamm has by far the highest favorability rating and recognition factor. But, there are two months left before the August 8 primary, which doesn't make her a solid lock. The person with the most to fear from the poll results may be Republican contender Rick O'Donnell. 
The lone Republican in the race, former Colorado Department of Higher Education chief Rick O'Donnell had 7 percent give him a favorable rating, 12 percent an unfavorable rating, 28 percent were neutral and 53 percent did not know him well enough to register an opinion.
