If you haven't read The Nation and you are a Progressive, you should. If you are a conservative, you should read The Nation just to find out how ridiculous your ideologies are. It is the top Progressive publication on the market and I have followed this publication for the last few years; it has strengthened my Progressive position more with each article read. Today, it endorsed Bernie Sanders.
This endorsement confirms with no doubt who the Progressive candidate is in the Democratic primary, placing Bernie Sanders in the position of being the people's candidate. If you're not sure what that means, it indicates the only one running for President who wants to put the middle class and the disadvantaged before the wealthy and big corporations.
It is an endorsement that Bernie can take to the bank. The Nation has endorsed Democratic candidates only twice. Jesse Jackson in 1988 and Barack Obama in 2008.
