The first part was enough..... "I am not aware of any". Nuff said.
   Mohawk;
  Just because Yelow didn't happen to..or didn't want top think of any restrictive measure by the boy/king..doesn't mean he hasn't tried..    So your "nuff said"..isn't !
   Let's take a look at the record above. 
      BTW: on the issues is a great, non-partisan site which gives "only the facts, mam". You can research any national politician there.
  Paragraph #1
  Obama voted AGAINST a homeowner defending him/herself with a gun..against a home invasion.
  Paragraph #2
       Obama calls for additional "common sense" laws concerning firearms. When a liberal calls for more "common-sense" anti gun laws, that means more 2nd amendment infringement..period!
  Paragraph #3
   Obama clearly lied about his stands against firearms ownership..does he do that regularly ?
   Paragraph #4
    Here's where he calls most of us "bitter clingers"..and goes on to say in the last sentence that he was raised by a 'single mother on food stamps".  Interesting; here is a woman with advanced degrees (probably financed by us) who can't support her son ?  How about the tremendous Kenyan father whom he patterns himself after?  does that mean he endorses refusing to support your children...let the taxpayer do it ?
   Paragraph #5
   Obama says 2nd amendment can stand (with "common-sense" changes, of course)...but it is alright if state and local governments outlaw gun ownership..Huh??   what???         ...How do we say "newspeak" ?
    Then toward the bottom he says George Bush ERRED in letting the "assault' weapons ban expire !  Interesting comparison there..No?
  Further down, some of his long term actions..
  A)  He wants to outlaw all semi-auto guns..
  B) He wants people who get shot by a robber to be able to sue  Colt, S&W, Ruger or Marlin...for what the robber did.  Of course, this would result in all gun makers being forced out of business..something would likely "warm the cockles of his heart"..
