If history holds true to form, I expect the presidential campaigns of Donald Trump and Kamala Harris to begin touting their support for the Great Lakes Restoration Initiative as Election Day approaches.

The Great Lakes Restoration Initiative, or GLRI, is a federal program that funds water and habitat protection and restoration for the Great Lakes, which contain over 20% of the world’s surface freshwater. While voters in some parts of the country may have never heard of it, it is a big deal in the eight states that border these inland seas.
