President Trump’s deployment of the National Guard from red states into blue cities isn’t just a partisan attack; it’s also a geographic one. In the 2024 election, Donald Trump won rural areas by 40 percentage points. And you could see what’s been happening in Washington, D.C., and Chicago as a rural political coalition militarily occupying urban centers. The rural-urban divide in America has become so big it’s dangerous — for our politics, and for democracy. And yet, just a few decades ago, this divide didn’t exist. Urban and rural areas voted pretty much in lockstep. And for Democrats to gain power again, they’ll need to figure out how to win some of those voters back. So how did the Democratic Party lose rural voters? And what could they do to win their votes back? Suzanne Mettler is a political scientist at Cornell University and the co-author with Trevor E.
