The Democrats are lauding Lincolns Emancipation Proclamation executive order as a fair comparison of Obama's order, but Lincolns order had no enduring resilience as the Dred Scott Decision would nullify it at the end of the war. All Lincoln could do was delay returning slaves to their owners. Obama's ploy is simply a stay of execution for deportations. He's buying time.
. . . You do know the slaves never were returned to their owners, don't you?
