In 2004 Obama co-sponsored S.B. 2386 bill that strengthened Illinois Stand Your Ground law. S.B. 2386 broadened the state’s Stand Your Ground law “by shielding the person who was attacked from being sued in civil court by perpetrators or their estates when a ’stand your ground’ defense is used in protecting his or her person, dwelling or other property.”
S.B. 2386 passed the Illinois state senate by a 56–0 vote on March 25, 2004. It sailed through the state house with only two “nay” votes. Both chambers were controlled by Democrats.
Stand Your Ground laws weren’t always much of a partisan issue. Florida’s law passed in 2005 after being approved unanimously in the state senate and on a 94–20 vote in the state house.
"There was little outcry about the change from minority communities. Perhaps that’s because, as The Daily Caller discovered, “African Americans benefit from Florida’s ‘Stand Your Ground” self-defense law at a rate far out of proportion to their presence in the state’s population.”
A third of Florida’s Stand Your Ground claims in homicide cases are made by African-Americans, a rate nearly double the black percentage of the state’s population. The majority of those claims have been successful, a success rate that exceeds that of Florida whites."
