Josh Hawley is a rarity in politics. Elected attorney general of Missouri last November, he’s held that office for five months. Yet he’s already under extraordinary pressure from Republicans to run for the Senate in 2018.

Senate majority leader Mitch McConnell and Missouri senator Roy Blunt have made it known they’re eager for him to run. And though Hawley is a conservative, leaders of the party’s moderate wing—notably former senator John Danforth and GOP donor Sam Fox—have publicly called on him to enter the Senate race.
