http://www.ontheissues.org/Celeb/Barack_Obama_Gun_Control.htmRecently, he has conceded an individual right to keep and bear arms, but supports local efforts at gun-control.
The problem is his past record of Chicago-style handgun bans (he somewhat disavows his record), and his desire to ban "assault weapons." This latter category is a made-up term used by gun-controllers and merely denotes a semi-automatic carbine of moderate power. The military does not recognize this term; they use "assault rifle," and it denotes a carbine of similar/same caliber which is capable of firing FULL AUTO (like a "machine gun").
The semi-auto carbines employ a technology which is over a hundred years old, and guns of this type have been used in this country by the millions for about as long (I have one built in 1905); in fact, the semi-auto AR 15 and AK 47 "clones" and others are now the most popular center-fire rifle (by sales) in the United States. Figures are not certain, but perhaps 12 - 15 million Americans own these "black" or "scary" guns. I have fired an AK clone: it has mild recoil, is accurate, and has cheap ammo. It may be the dominant rifle used on shooting ranges today (when I was younger the .22 rifle and far more power deer rifles were what you saw the most). Increasingly, they are being chambered for hunting purposes.
While right wing Republicans have pushed the sum-zero politics of gun control (notably Alberto Gonzalez, Sarah Brady, Bill Bennett, Charles Krauthammer, and yes, John McCain), the Democrats are tagged with it, with some justification. This is a problem.
It has been suggested by Jody in the Gungeon that Obama should declare that he will veto any legislation that seeks to infringe on the individual right to keep and bear arms. This would remove policy-making from the national level to the state level/local level where advocates on either side can hash it out in the courts, citing the 2nd Amendment, the 9th, the 14th, etc., as they see fit. If Obama were to do this, he would win back considerable support from "one issue" voters, I believe.
Ironically, the entire history of de jure gun-control is the history of de jure racism, ante-bellum, Jim Crow, industrial era. SEE: www.georgiacarry.org and scroll to the Heller brief. An eye-opener.
