Candidates and stakes
Senator Susan Collins, the last Republican remaining in New England’s congressional delegation, isrunning for re-election, testing whether a G.O.P. moderate can still hold ground in blue territory.
“The primary will be held on June 9”
Gov. Janet Mills and the progressive newcomer Graham Platner are challenging Collins, a five-term incumbent.

As the only Republican senator representing a state that voted against President Trump in all three of his races — Kamala Harris carried Maine by just under seven percentage points — Collins is reliant on cross-party voters, a group that has largely disappeared from national politics.
