But there are times when caution can keep a campaign from coming to grips with its essential challenge. For Bush, that challenge is overcoming the widespread suspicion that he lacks strong beliefs or convictions, that he bends with the wind. Taking a risk on debates could be his best way of shaking off that cansrd. 

可是有时谨慎可能使竞选不能面对重要的挑战。对布什而言,这项挑战就是去克服一般人对他的猜疑:他缺乏坚强的信仰或信念,见风转舵。冒险参加辩论可能是驱散谣言最好的方法。
