This is the fifth in a series of race rundowns designed to give subscribers a quick snapshot of what's happening in each district in 2018. Throughout the cycle, watch for our detailed analysis of the most closely-fought races in our competitive race overviews. And, be sure to bookmark our ratings to keep track of the latest changes.


ME-01: Chellie Pingree (D) – South: Portland, Augusta Solid Democratic. There was some speculation Pingree would run for governor in 2018, but she announced this week she will seek reelection. This Portland seat is solidly Democratic.

ME-02: Bruce Poliquin (R) – North: Bangor, Lewiston, "Down East" Lean Republican. President Trump clinched blue-collar northern Maine's lone electoral vote 51 percent to 41 percent, helping Poliquin win a second term. But he's highly vulnerable in 2018. The June Democratic primary will come down to conservation activist Lucas St. Clair (the son of a Burt's Bees founder), who could self-fund but whose recent Portland residency could be a problem, or Iraq/Afghan War veteran and state Rep. Jared Golden, who has deeper 2nd CD roots
