The Idaho Statesman and KBOI TV Channel 2 have commissioned a statewide poll by Mason-Dixon Polling and Research, a national polling company based in Washington, D.C., in advance of Tuesday's primary election, and the results are darn interesting. In the 1st District congressional race, among likely voters in Idaho's Republican primary in the district, the poll found 31 percent favoring Vaughn Ward, 28 percent for Raul Labrador, 37 percent undecided and 4 percent for Harley Brown. That's a statistical dead heat - the difference between Ward and Labrador falls within the poll's margin of error. You can read the Statesman's full coverage of the poll here.

In the governor's race, the poll showed Gov. Butch Otter with 60 percent, 25 percent undecided, and none of the five GOP challengers rising beyond single digits, with Rex Rammell highest at 6 percent followed by Sharon Ullman at 4 percent (my column taking a look at the primary race for governor runs in Sunday's paper; you can read it here). In the 2nd Congressional District, incumbent Mike Simpson was at 62 percent, undecided 23 percent, and challengers in single digits. The poll showed the contested Supreme Court race also in a dead heat, at least among Republican primary voters (it's a non-partisan race); incumbent Roger Burdick had 24 percent, challenger John Bradbury 20 percent, and 56 percent were undecided.
