Republican legislators in Sacramento are crying foul over an eleventh-hour push to limit future initiatives to November general elections. But the idea behind the union-backed legislation doesn't seem so bad to a majority of GOP voters, according to a new Field Poll. Registered Republicans supported the proposed change by a 15-point margin, 52 percent to 37 percent. Overall, 56 percent of voters back the proposal, which was approved by the Legislature and is now awaiting action by Democratic Gov. Jerry Brown.
