The poll released Friday was conducted by The Center for the Study of Elections and Democracy at Brigham Young University. It surveyed 417 voters earlier this month and 61 percent indicated they would vote against vouchers.

Only 39 percent of those polled favored the voucher law. And 90 percent of those who responded to the online survey Oct. 3-9 said they were very certain of how they would vote, even a month before the election.

A panel voters who were recruited on election day in 2004 and 2006 were surveyed in the poll, which had a margin of error of plus or minus 5 percentage points.

The results were very similar to the last two Dan Jones and Associates polls, conducted in July and earlier this month.

Leaders on both sides of the voucher issue said the poll numbers aren't necessarily a guarantee of what will happen Nov. 6.

Lisa Johnson from the anti-voucher Utahns for Public Schools said the results are nice to hear, but the campaign against the voucher program will continue until the election.

Utah Speaker of the House Greg Curtis, who is a voucher supporter, said that "polls are just polls."

The voucher program would allow Utah families to receive private school tuition vouchers ranging from $500 to $3,000 per student attending a private school.

The Legislature passed the bill and Gov. Jon Huntsman signed it into law, but opponents quickly got enough signatures to challenge it on the ballot.
