Former President Barack Obama endorsed his former veep, Joe Biden, for the Democratic nomination for President.
But, according to the NY Post, the endorsement may not help Biden.
Biden is hoping that Black Americans and liberal Americans will turn out to vote for Biden they way they did for Obama.
However, the Post argues his endorsements for other candidates have not led to victories.
In 2009 he backed John Corzine for Governor of New Jersey.
Chris Christie won.
