Maine oyster farmer Graham Platner is leading Sen. Susan Collins (R-Maine) by 9 points in polling ahead of their November faceoff.

The Pine Tree State Poll from the University of New Hampshire, released Wednesday, found that 51 percent of likely voters said they would cast their ballot for Platner while 42 percent said they’d back Collins. Another 2 percent said they would choose another candidate and 6 percent are undecided.

The findings resemble results from February, when the numbers showed the Democratic candidate with 49 percent support compared to the incumbent’s 38 percent. Platner rose as a front-runner for Democrats in the state after Maine Gov. Janet Mills (D) dropped her bid.
