Citizen activists could find it harder to get initiatives on next year's ballot in some states. Lawmakers in about a dozen states have advanced roughly 40 measures this year that would restrict or revamp the citizen initiative process. Many of those bills already have been signed into law. The new laws include limits on who can circulate initiative petitions and additional requirements on the content of those petitions. Several states also are proposing to raise the threshold needed for voter approval. Many of the new provisions come from Republican lawmakers in states where progressive groups have placed initiatives on the ballot.
