“Sen. Susan Collins and Graham Platner are locked in a neck-and-neck Senate contest in Maine, according to a New York Times/Portland Press Herald/Siena poll, as voters weigh a desire for Democratic control of the Senate against Ms. Collins’s record and controversy around Mr. Platner’s past conduct,” the New York Times reports.“Mr. Platner leads the race by two percentage points among likely voters, capturing the support of 49%, compared to 47% for Ms. Collins. It is a slight advantage, but one that is considered too small for polls to measure reliably, and which could easily grow or shrink as campaigning ramps up.”Nate Cohn: “On paper, this race has all the makings of a marquee matchup. A Republican political juggernaut is seeking re-election for the fifth time. Her opponent is a charismatic candidate with weaknesses some might see as disqualifying. And the contest is taking place in a challenging state and tough environment for Republicans. The narratives are straightforward and compelling.”“But the poll shows that none of those narratives are as solid as they might appear.”
