UPDATE, 10:30 p.m.: With nearly 90 percent of precincts counted, St. Louis County voters appear poised to enact a sales tax hike to send revenue to the St. Louis Zoo.

The measure that would add one-eighth of a cent to the sales tax has support from 60.8 percent of voters. The money would also go toward developing a new public attraction, such as a safari park. County residents would get free admission to the new facility, but others would be charged.
