A day after he proposed $40 billion in new federal education spending, President Clinton visited a central California middle school today to teach eighth-graders -- and, presumably, Bob Dole -- a history lesson. "It's very important that, at your age, you understand things about the history of our country and you understand what the time you're living in is all about," Clinton told children at Abraham Lincoln Middle School in Selma. To others who would listen, he added: "Education is not supposed to be a partisan political football, and it should not be when Congress returns." TIME's Michael Duffy says presidents have often used Labor Day weekend to clarify their legislative priorities and to set the tone for their re-election campaigns. Besides, Duffy adds, "Clinton can't win in '96 without California's 52 electoral votes."
