Eric Fey, a St. Louis County Election Board official, said the result potentially could change if any military or other overseas ballots cast by a Ward 1 resident postmarked by Tuesday arrive in the mail in the next few days.

But if the totals stay the same in the official certified count, Fey said, state law says the candidates can either get a runoff election or decide the outcome by a coin flip or a similar method.

In St. Charles, Borgmeyer, the retired head of a marketing company, and Faith, the mayor, had argued in their campaign over whether the city was on the right track in economic development.

Borgmeyer, 72, had complained that St. Charles has fallen behind nearby cities such as St. Peters and O’Fallon in attracting jobs-producing development and that he would be more aggressive in that regard.

Faith, 73, disputed that and pointed to projects such as the Streets of St. Charles mixed-use development and the planned expansion of the St. Charles Convention Center.

In Florissant, Lowery, 54, is following the career path of his late father, Robert Lowery, who was the city’s police chief for 22 years and mayor for 10.
