A drive to limit the terms of Florida politicians has cleared its first major hurdle toward the November 1992 ballot, organizers said Monday. "Limiting political terms is not merely a popular idea. It's becoming reality here in Florida," Orlando businessman Phil Handy, who is leading the drive, said at a news conference. The slogan for the drive is "eight is enough." To get a proposed constitutional amendment before voters through the initiative process, supporters must have their measure reviewed by the state after collecting 10 percent of the signatures needed to get on the ballot. Citizens for Limited Political Terms has reached that point, said Handy, who was finance chairman for former Gov. Bob Martinez's gubernatorial campaign in 1986. Handy said he was sure the measure would pass the requirement that it deal with only one subject. The amendment, which will go to Attorney General Bob Butterworth and probably the state Supreme Court for review, would limit state officials, including the six Cabinet members and 160 legislators, to eight consecutive years in office. It also would limit the terms of the 19 Florida members of the U.S. House of Representatives to eight years. Florida's two U.S. senators would be limited to 12 years. In the past three months, Handy's group has collected more than 50,000 signatures. Although signatures have been collected in all 67 counties, Orlando, the Tampa Bay area and Broward County showed particularly strong support, Handy said. Organizers have attracted about 1,000 volunteers and 500 financial supporters, who have contributed about $83,000 to the drive, according to Handy. If approved as meeting the single-subject requirement, to get on the ballot the initiative must collect 363,886 signatures _ 8 percent of the voters in the last presidential election _ by mid-1992. Additionally, 8 percent of the signatures must come from 10 of the state's 19 congressional districts.
