A current poll (yes its Democratic PPP) doesn't look good for Heather and worse for Pearce:
With a 56-27 approval-disapproval margin, Bingaman is more popular at home than all but four of the 77 colleagues which PPP has measured in the last year or so. This strong favor with his voters gives Bingaman formidable odds to walk to re-election, even against Johnson, whose 44-32 favorability rating makes him considerably the best liked of the non-Bingaman candidates, and who is almost equally popular with Democrats, Republicans, and independents.Johnson comes closest to beating the incumbent, yet still trails, 51-40. By comparison, Rep. Steve Pearce lags Bingaman, 57-34, and Rep. Heather Wilson trails, 56-37.
Bingaman safe, Johnson Dems’ only threat in open seat race
I suggest you look at the sample used....Q19.....55% Dem and 29% Rep....thats 11% more than 2008.
This NM poll was debunked by Jim Geraghty earlier. They oversampled Dems by a mile.
