Trio of Senate polls?

In the past week we have new polls from Rasmussen Reports, SurveyUSA, and Strategic Vision on the state's US Senate race, though the SurveyUSA poll I only have unsubstantiated information for as it is not posted on their website yet. The results:

Rasmussen Reports [I]: Maria Cantwell 46 [-2%] Mike McGavick 40 [+3%]
SurveyUSA [I]: Cantwell 53 McGavick 36 Adair 3 Dixon 3 Guthrie 3 (Edited with verification)
Strategic Vision [R]: Cantwell 48 McGavick 43 [-1%]

Rasmussen appears to have reverted to its consistent small Cantwell lead results and it's probable their July result of 48-37 was either an outlier or a brief result of Cantwell's initial ad blitz. The SurveyUSA poll would certainly be good for the incumbent if the source I caught it from is correct, though I'm curious if that is the case will the Democrats badmouthing their methodology last week (when they had Dave Reichert out to a decent lead) change their tune? In my experience, SurveyUSA is consistently fair and usually more accurate than any of the other major independent pollsters, robo-polling or not.
