Graham Platner’s triumph, explained by a Maine reporter
Can we read big national trends into Janet Mills’s defeat? Or are these candidates — and this state — just singular?
One of the most hotly contested Democratic primaries of 2026 ended with a whimper rather than a bang Thursday, as Maine Gov. Janet Mills (D) suspended her Senate campaign, making outsider oyster farmer Graham Platner the overwhelming favorite for the party’s nomination.
The seat, currently held by five-term Sen. Susan Collins (R), is one of Democrats’ top pickup opportunities. But the primary battle surfaced many fascinating tensions inside today’s Democratic Party.
What doomed Mills — anti-establishment sentiment, her age, a bad campaign, or all of the above? How did Platner survive what many expected to be a campaign-ending scandal? Were his bold left views an asset or a liability? And can we read big national trends into this outcome, or is it mainly about the particular candidates, and the quirky state, involved?
To answer these questions, I spoke with Alex Seitz-Wald, a longtime national political reporter who moved to Maine and now works as deputy editor for the Midcoast Villager, a local newspaper. Since Maine’s Senate primary captivated national attention, Seitz-Wald has been a sort of Maine politics whisperer — a Maine-splainer — to national reporters. Here’s what he had to say.

Janet Mills is the sitting governor and was Democratic leaders’ dream candidate to take out Susan Collins. It was believed by many that she alone could put the seat in play. Now she’s gone down to defeat by a little-known outsider candidate — what went wrong?
If I had to pick one thing that explains the Mills-Platner thing, she just ran a terrible campaign. I’ve seen dozens of Senate campaigns. I covered national politics for 15 years, and this is one of the most shockingly bad campaigns I’ve ever seen.
The question she never really put to bed, but that everyone had was: Did she really want to do this? She kind of dragged her feet on running, as Chuck Schumer and national Democrats were very publicly trying to encourage her to run. She ran this very lackluster campaign, not doing a lot of public events, not a lot of energy, a media strategy that felt very dated. And that was what she could control.
The stuff that she couldn’t control — her age was the biggest factor. She would have been 79 when she was sworn in. Last summer, when she got in was right off the whole Joe Biden fiasco, the loss of the presidency to [Donald] Trump.
So a lot of Democrats were very concerned about that. It was so fresh in people’s minds, so raw, and........
