Governor Vilsack supports toughening the legal standard for judging when someone is driving drunk. A bill stalled in the Iowa Senate would move the blood alcohol intoxication limit to point-oh-eight (.08). Governor Vilsack supports the bill. But Senate Republican Leader Stewart Iverson says the buck stops with him, and he’s not interesting in passing the bill. Iverson says Iowa’s drunk driving laws are already the toughest in the nation and there’s no need to lower the blood alcohol level two-tenths of a percent.
