I'm not familiar enough with his policies to be able to say which ones I like and dislike. 
Well that was honest and unexpected...
The policies that I have heard Bernie state (beyond his 40-year track record of voting for civil rights, gay rights, etc)...
Bernie wants to get rid of private for-profit insurance companies... who are basically just a middleman making your health insurance more expensive than it needs to be... this has been estimated to save the average American around $5,000 per year
Bernie wants to fix tax loopholes that let billionaires get away with paying a 5% tax rate on capital gains, while the middle-class is stuck with 35% federal + state tax + fica + medicare + social security...
Bernie also wants to reinstate GlassSteagall... which should have never been repealed, and is single-handedly responsible for the real-estate/stock-market crash/bailout a few years ago
https://en.wikipedia.org/wiki/GlassSteagall_Legislation (Cliff notes: prevents banks from gambling with your money)
Picture banks losing $50,000,000,000 playing SatoshiDice... then asking the US government for another $50,000,000,000 to continue gambling (nobody fixed the loophole allowing them to keep gambling)
Bernie wants to make college free for all citizens who wish to attend... Like many European countries have already done
Bernie is the man with the plan
