The president has an enormous amount of power. The executive branch has been steadily expanding its power since the beginning of the country.

Consider, for example, a Sanders DOJ vs. a Trump DOJ? (I suspect a Trump FBI would be primarily interested in cataloging and spying on anyone critical of Trump or of Muslim faith, essentially use COINTELPRO as a starting point, but make it better and stronger and do good deals). What about a Sanders DEA? EPA? DHS? The executive can do nearly anything if they are bold enough. The executive can ignore the judicial branch ("He has made his ruling, now let him enforce it"), the legislative branch (subpoenas from congress? About illegal leaks of classified information for political purposes concerning Valerie Plame? Please direct the law enforcement officers with weapons in your branch to serve them. You don't have any?)

I believe Sanders would refrain from using executive power to make things worse, while I am certain all of the other candidates would not refrain. Hillary will not differ from Obama nor does she claim to. Trump's shtick is to be an American dictator, an executive strong man who advocates violence and abuse towards anyone who disagrees with him and acts as an outlet for racism and hate and anger. Imagine if he had an army of FBI, DHS, NSA agents at his beck and call.
