The language finally approved is here. It would arguably affirm the strongest self-defense rights in the country.
Procedure: An Iowa Constitutional Amendment must be approved by both house and senate in two sessions separated by an election, i.e., two "General Assemblies" in our jargon. Then it must be approved by voters. The next step for this one is the senate where Democrats control things this year. Next is passage -- in identical form -- in the 2013 or 2014 session.
O. Kay Henderson, news director of Radio Iowa and a savvy reporter, says senate passage is unlikely. That may be slightly strong. Two years ago the conventional wisdom ruled out passage of shall-issue because of a Democrat senate and governor. But that was also an election year, and anti-gun lawmakers took a second look at citizen sentiment. They had a sudden epiphany revealing that shall-issue was a very statesmanlike policy indeed. We'll see.
