Progressive magazine The Nation endorsed Bernie Sanders Thursday, marking just the third presidential endorsement for the magazine in its 150-year history.

“We believe such a revolution is not only possible but necessary — and that’s why we’re endorsing Bernie Sanders for president,” the magazine’s editors wrote Thursday.

“Bernie Sanders and his supporters are bending the arc of history toward justice,” they added, noting Sanders’ positions on healthcare, Wall Street, education, foreign policy, and the minimum wage. “Theirs is an insurgency, a possibility, and a dream that we proudly endorse.”

The other two candidates the publication previously endorsed were Jesse Jackson in 1988 and Barack Obama in 2008. The magazine is also the first major national media outlet to endorse a presidential candidate in the 2016 election cycle.

“We do so now impelled by the awareness that our rigged system works for the few and not for the many,” the editors said. “Americans are waking up to this reality, and they are demanding change.”

According to CNN’s Brian Stelter, the endorsement will appear as the cover story of the magazine’s Feb. 8 issue.
