The Constitution of the CSA altered very little of the US Constitution except for explicit defenses of state sovereignty, slavery, low tariffs, and other issues central to Confederate political ideology. Why, then, did it change Presidential terms from a (then-unlimited) four-year cycle to a single one of six years? This would be more understandable if there had been recent experience of a strong Presidency, but all the ones since Jackson had been effectively nonentities. Was it just from the supposition that any leader who managed to shepherd the CSA to independence would be electorally unstoppable, so the framers decided to pre-limit him, as it were? Was Presidential term limit reform already a going debate in mid-19th century America that the CSA just decided to use its blank slate to modify?
