DES MOINES: A record turnout of 130,000 Iowa voters gathered in firehouses, school gyms, churches and other community commons Monday evening in the first major expression of voter sentiment in the 1996 presidential race. As Iowans gathered to make their decisions Monday evening, the real winner may be the candidate who virtually moved to the state months ago. Lamar Alexander, who has spent more time talking to Iowans about his hopes and dreams than any other GOP candidate, is expected to make a very strong showing in the caucuses. SaysTIME Managing Editor Walter Isaacson, "The key thing that characterizes Alexander's campaign is that he's been spending most of his time in a small plane making hops throughout Iowa. He's making the case that he is above the fray and is not the candidate of negative ads, a la Steve Forbes."
