The Nation has endorsed Sen. Bernie Sanders (I-Vt.) in the Democratic presidential primary, the first major publication to take a stand in the nominating race.

"He has summoned the people to a “political revolution,” arguing that the changes our country so desperately needs can only happen when we wrest our democracy from the corrupt grip of Wall Street bankers and billionaires," the publication's editors said. "We believe such a revolution is not only possible but necessary."

The progressive magazine's nod is the latest in a string of progressive endorsements for Sanders. He also has nabbed support from MoveOn.org, the Working Families Party and Democracy for America.

Sanders has gained on rival Hillary Clinton in early voting states. In New Hampshire, the Vermont senator is ahead of the former secretary of state in several polls, while Iowa surveys show Clinton's lead over Sanders decreasing. Meanwhile, Clinton's campaign has started to openly attack Sanders, criticizing his votes on guns as well as his health care position.

The Nation, which describes itself as "the flagship of the left," endorsed President Barack Obama in the last two general elections. During the 2008 Democratic primary, the magazine's editors praised Dennis Kucinich, then a congressman, as the candidate most in line with the publication's values. (Kucinich dropped out of the race after failing to make much of a dent in the early primaries.)
