The length of Maine's coastline
Press Herald - The Congressional Research Service lists Maine’s coastline at 228 miles and California’s at 840 miles, using a standardized “general coastline” method that excludes bays and inlets. By that measure, California’s coastline is more than three times the length of Maine’s, not the reverse.
The National Oceanic and Atmospheric Administration publishes more detailed measurements that include tidal inlets and other intricate coastal features. NOAA puts Maine’s coastline at 3,478 miles and California’s at 3,427 miles. Maine comes out ahead, but only slightly — nowhere near a 3-to-1 ratio.
According to NOAA, Alaska has by far the longest coastline in the United States at 33,904 miles, while the shortest belongs to New Hampshire, at just 13 miles. Altogether, NOAA estimates the total U.S. shoreline at about 95,471 miles.

- State auditor Matt Dunlap, who is running for Congress in Maine’s 2nd District, is taking heat over a more than two-decade-old antiabortion vote. Dunlap said Monday that a 2003 vote he took in the Maine Legislature in favor of a bill restricting abortion access doesn’t represent his stance on the issue today and pledged to “always fight for reproductive freedom” as he campaigns for Congress.
- The U.S. Senate primary between Gov. Janet Mills, 77, and Graham Platner, 41, has been described as a generational battle for the future of the Democratic Party — and nowhere is that clearer than in their online presences. Platner is trying to galvanize hyper-online young voters on Instagram and X, while Mills is playing to older audiences on Facebook.
- Last year, at least one in 10 students was homeschooled in more than 50 school districts, largely in central and northern Maine. Since the pandemic, the number of home-schooled students has jumped from 3.6% in the 2019–20 school year to 6.4% in 2024–25. The growth comes amid years of school disruption, parental confidence in home education, and a 2021 law removing religious and philosophical exemptions for required school vaccines.
