Lincoln actually said that he’d work to get Dred Scott overturned, not unlawfully ignore it:
“He believed the court’s opinion was “erroneous” and the Supreme Court had often overturned erroneous decisions. Lincoln noted, “and we shall do what we can to have it to over-rule this. We offer no resistance to it.” - See more at: http://blog.oup.com/2015/03/abraham-lincoln-roger-taney-dred-scott/#sthash.LJdrtZVG.dpuf
He ignored it the same way O’Zero ignored the DOMA from the minute he became president. The lawless SOB told Holder not to enforce a law of the land passed by Congress. That started the country on the road to queer “marriage”. Ask Larry Sinclair why Zero has an obsession with fags? He’ll tell you in a heartbeat.
