If you want to see results that definitely are backwords between two candidates, see
http://www.maine.gov/sos/cec/elec/2006g/gen06s.html and scroll down to North Yarmouth in Cumberland County, Glenburn and Kingman Township in Penobscot County, and Monson in Piscataquis County. What do you think the chances are that those are the four municipalities where there was a descrepency in the reported votes for Slavick (an anti-war Independent from Portland; just the type who would appeal to voters in small northern Maine towns and a Portland exurb [sarcasm]) and Snowe? Snowe's one-vote loss in Grand Isle in the St. John Valley is believable (she lost it by one vote in 2000 as well, although Collins carried it this year by 10 points which shows how badly Tom Allen did in northern Maine), and her only getting 45% in No. 27 Township in Washington County (still carrying it by one vote over Slavick, 14 to 13, with 4 votes for Democrat Jean Hay Bright) is odd but results like that can happen in places with such a small number of votes.
