The tyranny of the legislature is really the danger most to be feared, and will continue to be so for many years to come."—JEFFERSON.
Both are correct. However, Jefferson is writing in the 1800's, and that is more the style of writing at the time, with a tone of rhetoric.
It's the same as saying, "There's a lot to be frightened of" (causual, colloquial) versus, "There is much to fear." (formal, as in a speech by a politician)
