The 6 biggest policy differences between Bernie Sanders and Hillary Clinton [View all]
http://www.vox.com/2015/5/1/8530439/bernie-sanders-hillary-differences
1) Money: Sanders attacks the rich; Clinton wants to raise money from them
Clinton wants to win the support of the wealthy and corporations to her side. Sanders wants to attack them and try to break their power. As Dylan Matthews wrote, the top organizations whose employees give to Sanders are overwhelmingly unions while for Clinton they're mostly banks and corporations. That fundamental difference in approach would almost certainly continue on from their campaigns to their administrations.
2) Trade: Sanders is extremely skeptical of new agreements, while Clinton has waffled
Trade is an issue on which the personal preferences of the president make a huge difference, regardless of who controls Congress. Since trade agreements are negotiated by the executive branch, a president can either choose to pursue new ones, or put them on hold entirely.
3) Foreign policy: Clinton is more of a hawk than Sanders and most other Democrats
On foreign policy issues involving the use of American force abroad, it's actually Clinton, not Sanders, who's most out of step with the Democratic Party. And since the president has broad authority to conduct foreign policy without Congressional oversight, this matters quite a bit. "It's very clear that a President Clinton would bring far more hawkish instincts to bear on global problems than the current president or, for that matter, your average Democratic voter," Zack Beauchamp wrote earlier this year.
5) Spending: Sanders wants big spending
Most Democrats would love to increase federal spending on their favorite policy priorities. But mainstream politicians in the party have recently tended to embrace messaging about fiscal discipline. Clinton wary of being tarred as a big-spending Democrat, like her husband was in the beginning of his administration is one of them, generally proposing that increases in spending would be paid for by other spending cuts or tax hikes.
