Maine Gov. Janet Mills drops out of Democratic primary for U.S. Senate seat

Maine Gov. Janet Mills is suspending her Democratic primary campaign for US Senate, clearing the way for Graham Platner to challenge Sen. Susan Collins. This move comes as Mills had been struggling in the polls, and her suspension of the campaign allows Platner to potentially win the party's nomination. The suspension marks a significant shift in the Democratic primary race in Maine, which is seen as a key state in the country's presidential election landscape.
