Salazar's campaign is touting the results of a poll showing him leading Coors 48-42. A Tarrance Group poll commissioned by the Coors camp had him trailing 47-43. The polls seem to be free of the Democratic oversampling we've seen so much of.
Nevertheless, both polls were taken before the Republican convention. Now the conventions focused on the Presidential nominees, and Coors's speech wasn't broadcast live. However, the Rasmussen tracking poll has shown a persistent bounce for the generic Republican Congressional candidate since the convention.
Clearly, this is still a very close race, but it's also almost certainly closer than the Salazar camp's email wants you to think.
