A new poll in the Minnesota governor's race -- could this be the last? -- again shows a close race for governor and gives Democratic candidate Mark Dayton a skinny lead.

Dayton got 43 percent in the poll, Republican Tom Emmer got 40 percent and Independence Party's Tom Horner got 15 percent, according to the poll from Public Policy Polling.

The pollster said they interviewed 2,058 likely Minnesota voters between Wednesday and Friday and gave the poll a 2.2 percent margin of sampling error. But he pollster added "other factors, such as refusal to be interviewed and
weighting, may introduce additional error that is more difficult to quantify."

Recent polls have all given Dayton an edge but some, like this one, show a narrow race between Emmer and Dayton and others have shown Dayton well ahead. The main thing the flurry of polls leading up to Election Day has agreed upon: Horner is in a distant third.

The poll also holds little good news for outgoing Republican Gov. Tim Pawlenty.

"Only 43% of voters in the state approve of the job Pawlenty is doing to 50% who disapprove. And the state expresses little enthusiasm for a 2012 Pawlenty White House bid with only 23% supportive of the idea and 59% opposed to it," the pollster said.

The poll also asked for ratings of Minnesota two U.S. Senators and, interestingly, Democrat Amy Klobuchar is out of the stratospheric positive zone. When PPP polled last spring, her approval rating was above 60 percent and the highest the pollster found among senators during that polling period.

Now, she has a 52 percent positive job approval rating.

Still that's better than Democratic U.S. Senator Al Franken.

His job approval rating was 44 percent -- exactly the same as his disapproval rating.
