This is a reminder that the House controls taxes. Not the President.
To oversimplify, a President can really (and reliably) do three important things: appoint federal officials (i.e. SCOTUS nominees), command the military and veto legislation. They also have, at least in theory, control over Executive Agencies.
Policy proposals involving legislation - i.e. most of them - are just talk unless you've got a hold on both Houses of Congress. Which a Democratic president elected in 2016 almost certainly would not - the GOP has a hold on the House.
So when Bernie Sanders starts talking about his policies (e.g. tax policies,) it's good to remember that anything involving legislation would get nowhere. It's the policy he doesn't talk about - the way I imagine he'd deal with the FBI, the CIA, the DEA, etc. - that I found appealing enough to give him my support. But he won't be the nominee, and disappointed Bernie supporters need to come to terms with that. Because only one party has a realistic chance of controlling Congress and the Executive branch, and it's not the Democratic one.
