Sen. Bernie Sanders (I-Vt.) has long considered a 2016 presidential candidacy. On Friday, he told The Associated Press he'd decide by March.
"I don't want to do it unless I can do it well," he told The AP. "I don't want to do it unless we can win this thing."
Sanders, who caucuses with the Democrats, has served eight terms in the House and is now in his second in the Senate. He's debating whether he would run as an independent or take on Democratic candidates in the primary.
