In fact, like Republican Donald Trump, Lincoln was the outsider come to shake things up in Washington beginning with the item Mary Chesnut seems most piqued about: hiring all their own people.
Much is made about the long months it took Lincoln to individually fill Washington's government posts, and so Congress passed new laws to make transitions "easier".
But the result is many Democrat partisans remained in office to snipe at and undercut the Trump administration, which was powerless to fire them.
Like Trump, Lincoln also had trouble finding good people for his administration, but I don't think he faced anything like the Deep State opposition to Donald Trump.
The exception proves the rule: Democrat SCOTUS Chief Justice crazy Roger Taney!
