WAUKESHA, Wisconsin—Bold was the word of the day at Scott Walker’s formal announcement of his presidential campaign.  Repeatedly the word was ladled over the sweltering supporters gathered in a local expo center that took on the close and aromatic aspect of a sweat lodge. Speaker after speaker testified to Walker’s boldness before he walked the runway to his place in the middle of the boisterous crowd. The candidate used the word a couple of times himself.
