Pete and Chasten Buttigieg celebrated their first wedding anniversary on Sunday. You know this if you’re among Pete’s roughly 1.1 million Twitter followers or Chasten’s 340,000, because they traded sweetly effusive missives, as they frequently do.

Pete gushed: “One year ago I married the love of my life. I’m so thankful I found you, Chasten, and can’t wait to spend the rest of our life together.” Chasten posted pictures of the two of them with their arms around each other, which he introduced by writing that he was on his way “to find this cute guy on the trail. Can’t believe it’s been one year.”

Two months ago, when they kissed during the event that marked the formal beginning of Pete’s presidential campaign, one headline called it a “radical moment.” But what has happened since — their daily and sometimes hourly displays of the commitment, respect and brimming sentiment that go into the best romantic partnerships — is more significant and potentially transformative.

They aren’t just the first gay couple at the forefront of a presidential race. They’re the 2020 campaign’s most public love story, one that makes it difficult for even the most resistant Americans to see a same-sex relationship as some frivolous romp, freakish affront or carnal curiosity.
