Illinois State Rifle Association
Quote from the first link:
Although Obama claims to be an advocate for the 2nd Amendment, his
voting record in the Illinois Senate paints a very different picture. While
a state senator, Obama voted for a bill that would ban nearly every hunting
rifle, shotgun and target rifle owned by Illinois citizens. That same bill
would authorize the state police to raid homes of gun owners to forcibly
confiscate banned guns. Obama supported a bill that would shut down
law-abiding firearm manufacturers including Springfield Armory, Armalite,
Rock River Arms and Les Baer. Obama also voted for a bill that would
prohibit law-abiding citizens from purchasing more than one gun per month.
Without a doubt, Barack Obama has proven himself to be an enemy of the
law abiding firearm owner. At the same time, Obama has proven himself to be
a friend to the hardened criminal. While a state senator, Obama voted 4
times against legislation that would allow a homeowner to use a firearm in
defense of home and family.
