The most erudite politician in our fair county is also the most important one. Under the guidance of Fort Lauderdale Mayor Jack Seiler, Broward County has an unemployment rate of 5.7 percent — substantially lower than the state and national averages. More than 13 million tourists are expected to deluge Broward County this year, which marks an increase of 1 million over last year. And while Seiler doesn't deserve credit for all of this, he leads the most dynamic and biggest city in the county. He also deserves major props for not making a mistake that has bedeviled other politicians: excessive ambition. There was a time when Seiler was considering a run at governor. This would have been a mistake — established state pols like Charlie Crist or Rick Scott would have pummeled him — and he wisely backed out. For now, it looks like Seiler's here to stay. And that's a good thing.
