mccain campaign put together to use against mitt romney in the republican primary. in 1994 when mitt romney first ran for senate, he backed the brady bill and the assault weapons ban. as governor of massachusetts, mitt romney upped the cost of gun licenses four fold and promised on the campaign trail to not chip away at gun laws. >> we do have tough gun laws in massachusetts. i support them. i won't chip away at them. >> he did not. in 2004 governor romney signed the permanent assault weapons ban in massachusetts. then mitt romney decided to run for president. he started prepping himself for the republican presidential primary and then, of course, things got hilarious on the subject of guns. mr. romney said in a debate with "the boston globe," quote, i have a gun of my own. i go hunting myself. to which someone in the room replied, and i quote, excuse me, but isn't that your son josh's gun?
