NRO political reporter Jim Geraghty and political journalist Jon Ralston have both rightly figured Nevada’s “none of these candidates” ballot option into the Reid-Angle electoral equation, although the Las Vegas Review-Journal this morning cited numbers from the new Mason-Dixon poll and said it may be less of a factor than previously thought:

Only 5 percent of voters were undecided, 2 percent picked “other” candidates and 3 percent chose “none of these” candidates, a protest category that’s shrinking, defying predictions of some pundits.

Nine weeks before early voting begins, it is far too soon to say how many voters will prefer “none” to Reid, Angle or any of the other candidates available to them. And as Ralston pointed out, another major factor is whether the get-out-the-vote machine of the Democrats can get people to the polls on election day:

If Reid wins, it is this advantage that will be decisive; if he loses, it will mean people refused to be dragged out of their homes to vote for him.

All present indicators point to this race being close. If the final spread is less than five points, it may be the stay-at-homers and none-of-the-abovers rather than the party faithful who determine the result.
