The "trend line" presented here is stretched over such a long period, that it's almost not worth including. Lest you think that the Humphrey Institute's methodology is giving Franken a boost, keep in mind that Franken was running very close in other surveys from SurveyUSA, Rasmussen, and even the GOP firm McLaughlin & Associates in the early part of the year.
