I was involved in gathering signatures for that initiative. The problem was apathy on the part of gun owners.

Most people talk a really great game, but when it comes time to hit the field, they head for the showers instead. People refused to sign the petitions because "I don't sign those things" "I don't want my name on any list" "It won't do any good". That's just the excuses i heard at gun shows.
The local NRA was no help. The CRPA was no help. We couldn't get enough volunteers to collect signatures. One of the largest gun stores in the area wouldn't let me leave petitions because "It might actually hurt our cause". One store owner "Didn't have time to mess with it".
But the biggest problem is the voters. We had a chance to put a real pro gun governor in office, but instead put that RINO Kennedynagger in office.
Sorry for the long rant, but you asked.
