Leaving out Jefferson and Lincoln, we haven’t had very good luck with presidents who are lawyers.
Considering that Lincoln had the army break in to newspapers that wrote against the war and smash their presses I wouldn’t put Lincoln in greatest respecters of the constitution column.
He also banished a former Ohio member of the House of Representatives who was a vocal political opponent of Lincoln to Canada. A Copperhead who believed it was the right of the states to secede.
