Is it a comprehension problem? Totally the opposite. The power to suspend the writ is a power delegated to the legislature. The legislature creates the court system - the The Judiciary Act of 1789 created the US courts including the Supreme Court, 'Be it enacted, That the supreme court of the United States shall consist of a chief justice and five associate justices ...'
The Confederate Congress DID fail to create the Supreme Court, but the President does NOT have legislative powers. The fault was not attributable to President Davis, but to the legislature.
The post to which you replied was done tongue-in-cheek at those that think the President can exercise ANY power in time of war, or because he is not prohibited from doing so.
Like I've said all along, Davis failed to abide by the confederate constitution aided and abetted by the confederate congress. Where have you been? Yet contempt of constitution seems to be a point of pride for supporters of the Davis regime.
