Jeff Davis didn’t order this usurpation, the goon OTH not only ordered usurpations he demanded it.
What usurpations? Suspending habeas? Davis did that. Shutting down newspapers? The confederates locked up their first newspaper editor one day after Ft. Sumter was shelled. Davis unilaterally extended the enlistments of his soldiers, abrogating their contract. Under Davis, Confederate forces spread terror among Unionist areas of the south.
And unlike Davis, Lincoln actually ran for election, twice, against opposition. Davis ran unopposed and won 97% of the vote, a total that sounds rather like those out of Saddam-era Iraq or North Korea.
