About 49 percent surveyed in the telephone poll conducted June 18-19 supported the amendment while 48 percent said they were opposed. The rest were undecided. The poll of 600 randomly selected adults has a margin of error of plus or minus four percentage points.
Other polls conducted earlier this year have shown a higher percentage in favor of the proposal, typically around 60 percent in favor and 40 percent against.
There's a trend.
Wisconsin Republicans hope the issue will help them bring conservative and religious voters to the polls in their bid to defeat Democratic Gov. Jim Doyle, who opposes the ban. His Republican challenger, Mark Green, favors the constitutional amendment.
Meanwhile, a new poll shows Doyle 13 percentage points ahead of Green. And, incredibly lamely, the Republicans don't even have a serious candidate running against Senator Herb Kohl. (But you can blame Tommy Thompson for that.)
