From the AP, via Portland Press Herald:

PORTLAND - Sen. Susan Collins held a 20-point lead over Rep. Tom Allen in the 2008 Senate race, while candidates vying for Allen's congressional seat showed little success in distinguishing themselves in the minds of voters, according to a poll released Friday.

The Critical Insights poll, which touched on a range of topics of interest to business, government and the general public, found 54 percent support for Republican Collins and 34 percent for Democrat Allen. Twelve percent were either undecided, didn't know or refused to say.

The poll also shows that none of the candidates for Allen's soon-to-be-vacated First District House seat have more than 4% name recognition.
