First off "...all men created equal..." is the DECLARATION not the constitution which before LINCOLN stated that slaves were 3/5th a human being...

Second THE CONSTITUTION STILL READS: 
Art 1 Sec 9 Cl 2:
The Privilege of the Writ of Habeas Corpus shall not be suspended, unless when in Cases of Rebellion or Invasion the public Safety may require it.

the FACT that LINCOLN jailed the Maryland Reps who were meeting specifically to SECEDE(aka dissolve UNION aka TREASON) and the newspapers & journalists who incited TREASON...was NOT UNLAWFUL...as opposed to what is being done to SNOWDEN & the whistle-blowers- it WAS HIS DUTY TO PRESERVE THE UNION

Finally LINCOLN was a southerner- BORN IN KENTUCKY

so maybe you should try FACT checking b4 posting
