A mid-October poll by the same group showed Trauner leading Lummis 44-43%, with 4% supporting Libertarian W. David Herbert and 9% undecided.

Cubin had been a lightning rod for controversy over a number of incidents that ranged from receiving money from ARMPAC, to distributing penis-shaped cookies to male colleagues while in the Wyoming Legislature, to even an incident after a televised debate in which she remarked that if the Libertarian candidate, Thomas Rankin, who has multiple sclerosis and must use a wheelchair, "weren’t sitting in that chair," she would have slapped him in the face.

After Zwonizter withdrew, Green River physician and Ron Paul backer Mike Holland jumped into the race.

After anonymous circulation of two mailings attacking him personally, Gordon became critical of Lummis' campaign and hence aired ads about her past voting record of increasing taxes.

Lummis countered with criticism of Gordon's past funding of Democrats Trauner, Governor Dave Freudenthal in 2006, and John F. Kerry for president in 2004.

Trauner's massive war chest from the DNC contributed to his TV ads swamping television across the state, while Lummis had very little money left from her expensive primary battle.
