If there were a worldwide contest for the most USA couple in the world, Tim and Demi-Leigh Tebow would be trading very high on Polymarket. They check all the boxes of peak first-quarter-of-the-millennium Americanism: she is a former beauty queen and he is a former NFL quarterback and pro baseball player. They both do a lot of motivational speaking. They go to church together on Sundays. They watch Ted Lasso and The Chosen. They both have millions of followers on social media. And they were both briefly but blindingly famous.
