Latest Poll Shows Musgrave At 46%

The latest Denver Post/Mason Dixon poll in the 4th Congression District shows incumbent Republican Marilyn Musgrave leading Democrat Angie Paccione by 10 percentage points.  Reform candiate Eric Eidness was favored by 7%.

Musgrave 46%
Paccione 36%
Eidness 7%
Undecided 12%

This is the fifth poll in the race released since mid-August (three independent, and one internal poll from each candidate).  All show support for Musgrave in the 42%-46% range.  All show support for Eidness in the 5%-8% range.  Support for Paccione, which has ranged from 36%-42%, has been higher in two prior Survey USA/KUSA polls which have a low undecided percentage, than in the Mason-Dixon poll and Musgrave internal poll, which showed higher undecided percentages.  Taken as a whole, these results are in accord with the conventional wisdom that undecided voters tend to strongly favor challengers over incumbents when pushed.

As the race stands, Paccione needs about 92% of of the undecided votes in the Mason-Dixon poll to win, which indicates that she is likely trailing in the race, if the poll is accurate.  But, a 10 percentage point lead probably significantly overstates the extent to which Musgrave is really leading in this race, which is likely closer to 4-6 percentage points, assuming that two-thirds to three-quarters of undecided voters break for a challenger, which would be typical.

Mason-Dixon Poll Details

The Mason Dixon poll sampled 400 registered voters from October 3-7, with a margin of sampling error of +/- 5 percentage points.

Among Democrats, the split was:

Musgrave 7%
Paccione 85%
Eidness 0%
Undecided 8%

Among Republicans, the split was:

Musgrave 77%
Paccione 3%
Eidness 9%
Undecided 11%

Among unaffiliated voters, the split was:

Musgrave 39%
Paccione 33%
Eidness 10%
Undecided 18%

The number of greatest concern to Paccione is the lack of a strong lead among independent voters, which is essential in the Republican leaning 4th Congressional District.  Of course, the margin of error within a subsample like unaffiliated voters far exceeds that of the poll as a whole.
