Maine Governor Janet Mills' Senate bid has effectively ended after she suspended her campaign, citing a lack of financial resources.
The move clears the Democratic field for newcomer Graham Platner, who has been outraising Mills and polling well in the state.
Mills' campaign was initially boosted by a tense confrontation with President Donald Trump over transgender athletes in sports, but it failed to translate into lasting momentum.
During the confrontation, Mills told Trump 'See you in court,' a phrase that became a rallying cry for Democrats nationwide.
However, Platner's populist message and fundraising abilities have given him a significant advantage in the campaign.
