Maine: Marist Survey Shows Democrats Leading Both Statewide Races

Two new surveys out of Maine point to a Senate contest still within range of a flip, even as the state's governor's race looks increasingly settled. A Marist University poll completed October 4 found Democrat Troy Jackson leading Republican Susan Collins 51% to 47% among registered voters in the Maine Senate race. A Maine People's Resource Center survey completed five days earlier, on September 29, showed a narrower 49%-47% Jackson edge among likely voters — a gap within the margin of error and a reminder that registered-voter samples tend to flatter the party doing better among less-engaged respondents.

The discrepancy between the two polls is modest in absolute terms but matters for how the race gets read heading into the final weeks. A four-point Marist lead among registered voters and a two-point edge in a likely-voter screen are not contradictory findings, but they do suggest Jackson's advantage softens once pollsters apply turnout assumptions — typically the more predictive of the two methodologies this late in a cycle. PollingSource continues to rate the race a toss-up, and nothing in either survey moves that designation. Collins has built a career on outperforming her party's statewide numbers in Maine, and a four-point deficit in one poll, or a two-point one in another, is well within the territory she has overcome before. Whether that history still applies in a midterm environment shaped by national dynamics is the open question the toss-up rating is meant to capture.

The governor's race shows a different pattern entirely. The same Marist poll put Democrat Hannah Pingree ahead of Republican Bobby Charles 52% to 40% in the Maine governor's race — a twelve-point spread that lines up with PollingSource's existing Safe D rating rather than complicating it. A margin that size, more than double the Senate gap in the same poll and same field dates, indicates the governor's race and the Senate race are being shaped by largely different dynamics: one a genuine toss-up sensitive to late movement, the other a contest where the floor for the Democratic candidate appears considerably higher.

That divergence is itself worth noting. Maine voters appear willing to back Pingree by a wide margin while treating the Senate race as a closer call, which cuts against any simple narrative of a uniform partisan wave moving through the state. Split-ticket behavior of this kind — if it holds — would be consistent with Maine's recent electoral history, where statewide results have not always tracked neatly with national partisan trends. The Senate race remains the one to watch for signs of where that pattern breaks.
