DES MOINES, Iowa (AP) — From raising the minimum wage to legalizing medical marijuana, some bills in the Iowa Legislature have an uphill battle that isn’t so steep in some other statehouses. Two dozen states have a system that allows residents to bypass lawmakers and place proposed initiatives on an election ballot. The system varies by state, but the idea is that citizens should have an option B when it comes to enacting potential laws. Iowa doesn’t have such a system, and that means state lawmakers might face a little less pressure to pass certain bills, much to the frustration of some residents seeking action. Despite that, there seems to be a consensus among Iowa lawmakers that the current system should remain and that approving an option B could complicate things.
