There will be a runoff next month in the Galveston mayoral race. It’s down to incumbent Joe Jaworski and challenger Lewis Rosen. Rosen earned more votes than Jaworski in Saturday’s election. But neither reached the 50 percent needed to avoid a runoff. This campaign has been dominated by a stubborn, unresolved question — how should the city replace public housing lost to Hurricane Ike? When Hurricane Ike tore through Galveston in September of 2008, it damaged or destroyed nearly 600 public housing units. Mayor Joe Jaworski says that gave the city a rare opportunity to start fresh by bulldozing projects that, in his opinion, shouldn’t have been around as long as they were.
