Whatever mistakes the Florida doctors may have made in their campaign, they seem to have benefited from a recent upsurge in public support. A poll reported Oct. 30 in the Tampa Tribune and WESH-TV found that 48 percent of Florida voters were planning to vote "yes", 39 percent "no", with 13 percent undecided. That's a marked improvement from polls only a week or two earlier which had found the measure trailing.
