Down goes Christie:

QuoteRepublican presidential candidate and New Jersey Gov. Chris Christie on Tuesday denied that the issue of gun control motivated him to run for the New Jersey state Senate two decades ago, despite the fact that he said so at the time.

In 1993, Christie, then 31, attempted unsuccessfully to unseat John Dorsey (R), the state Senate majority leader, after the New Jersey GOP attempted to repeal the state's semi-automatic weapons ban.

"The issue which has energized me to get into this race is the recent attempt by certain Republican legislators to repeal New Jersey's ban on assault weapons,' Christie said in an April 14, 1993, statement, according to the New Jersey Star-Ledger. ''In today's society, no one needs a semi-automatic assault weapon."

But when asked by Fox News' Brett Baier on Tuesday whether it was true that gun control -- something no Republican presidential hopeful wants to be associated with -- "inspired" him to enter politics, Christie said it was not.

 
Honestly, he never had a chance anyway.

Yeah, but Christie would demonstrate he pardoned that guy who was sent to prison for transporting his guns because he was moving to a new residence.  CC caught hell from the libs... whose position I guess is, if you move to a new house your guns have to stay at the old one.

Aiken, or Adkins.. justa sec...

Aitken...  who was banned from seeing his son till Christie commuted the sentence.  And I think the Governor caught hell from some on the Right for pandering to them.

Personally, I don't think Christie knew what 'semi-auto' meant back in the 90's.  As most libs didn't...  I think CC will struggle somewhat with his 'lie', but not enough to effect his already-underwater campaign.
