Humor me. Name the "great parts" Lincoln "suspended."
The writ of habeas corpus
The first amendment via suppressing dissenting newspapers
The second amendment via widespread gun confiscation
The doctrine of the separation of powers via harassment of the judiciary
Splitting a state, Virginia, without its consent
Instituting an income tax
Amendments 4, 5, and 6 through the suspension of the civil authority
...and those are just a few of them.
