Gallup also produced a model anticipating slightly higher turnout.
Under this model, the Republicans led by 13 points, which is still an
historic result in the Gallup model. Among registered voters,
Republicans led by 3 points.
Rasmussen Reports, by
contrast, saw the race tightening significantly, with Republicans
leading Democrats by only three points, 45 percent to 42 percent. This
represented the closest ballot test in roughly a year. Of course, the
big difference between the two polls is the number of undecideds; it may
well be that Democrats are truly stuck at around 40 percent, and
undecideds are leaning heavily GOP."
