Salvadorans are voting in an election Sunday that is widely expected to hand Nayib Bukele, the self-described “world’s coolest dictator,” a second term as president. El Salvador’s constitution prohibits reelection, but his supporters have largely shrugged off such concerns. Nor has his popularity been hindered by allegations of chipping away at El Salvador’s system of checks and balances while tackling gang violence.

Though crime has plummeted, and Salvadorans have retaken their neighborhoods, the massive arrests have been criticized for a lack of due process.El Salvador’s traditional parties from the left and right that created the vacuum Bukele first filled in 2019 remain in shambles.

Since Bukele began his crackdown, that fear has dissipated. Bukele made no public campaign appearances in the run-up to Sunday’s vote. Instead, he drove home the message – via social media and television ads – that the crackdown on gangs would be in jeopardy if his New Ideas party didn’t win.
