NEW POLL: WILSON AND PEARCE NECK-TO-NECK

The new SurveyUSA poll shows U.S. Rep. Steve Pearce beating Rep. Heather Wilson by just one point in the Republican Senate primary.

Two weeks ago Pearce was leading by three points in the SurveyUSA poll. And the Albuquerque Journal poll, published on Sunday showed Pearce up by six points.

One big difference in the polls. As Brian Sanderoff has explained to me many times, automated polls like SurveyUSA tend to record fewer undecided votes because undecided voters tend to hang up early in the phone call. Indeed the latest SurveyUSA poll shows only 3 percent undecided, while the Journal poll (conducted by Sanderoff) showed 16 percent undecided.

SurveyUSA's poll has a 4.5 percent margin of error.

The new poll shows both Wilson 24 percent behind Tom Udall while Pearce is 25 percent behind Democrat UDall.
