Raye's first contest with Michaud came in 2002, the year Michaud was elected to the House. Raye won the GOP primary, but Michaud used his work for Snowe in the Senate to paint him as a Washington insider, and Raye lost by five points.
Michaud won his last reelection by 10 points, and the district leans Democratic, having supported President Obama in 2008 and Sen. John Kerry (D-Mass.) in 2004. But Snowe, one of the most popular Senate Republicans, will be on the ballot in November, which could give Raye a boost if he wins the primary.
The poll of 400 likely Maine voters was conducted Jan. 23-25 using live telephone interviews and had a margin of error of plus or minus 4.9 percentage points.
