Palm Beach voters appeared to favor a half-cent sales tax to support schools. The tax would replace a one-cent tax that was agreed to eight years ago. The measure had the support of about 60% of voters at about 9:15 p.m. Tuesday, with all early voting in and 759 of 798 Election Day precincts in. The new tax would lower the total sales tax from 7% to 6 1/2%.
