GPI update; Emmer below 30 again

MPR/Humphrey (10/28, likely voters, 9/29 in parentheses):

Mark Dayton (D): 41 (38)
Tom Emmer (R): 29 (27)
Tom Horner (I): 13 (16)
Undecided: 20 (20)
(MoE: ±5.5%)

MPR released it's last poll of the Governor's race this morning and they don't find a whole lot has changed since last time, other than Horner losing a few points to the other two candidates, which other polls had already shown.

If the undecided number seems high, it is, but The Humphrey Institute lumps undecided into the same category as "don't know," "refused," and "voting for someone else." It would be nice to see what the undecided number is all on it's lonesome.

The Pollsters Dilema

What's up with SurveyUSA's 18-34 polling and other observations

This post is the result of a back and forth I had with Aaron Klemz at The Cucking Stool in the comments of his post about the age gap in the most recent SurveyUSA poll of the Minnesota Governor's race. This was my initial comment:

This has been a trend for SurveyUSA all year and not just in Minnesota. I find these numbers hard to believe and suspect they have more to do with a flaw SurveyUSA's methodology when it comes to young voters. Perhaps it's an issue with cell phones perhaps it's the fact that they are an automated pollster, who knows.

The more I've thought about this the more I think it's an issue deserving of discussion outside of a comment thread.
