Known as the "Silent Senator", Hayden rarely spoke on the Senate floor. Instead his influence came from committee meetings and Senate cloakroom discussions where his comments were given a respect comparable to canon law. A colleague said of him, "No man in Senate history has wielded more influence with less oratory," while the Los Angeles Times wrote that Hayden had "assisted so many projects for so many senators that when old Carl wants something for his beloved Arizona, his fellow senators fall all over themselves giving him a hand. They'd probably vote landlocked Arizona a navy if he asked for it." (Source)
Almost a force of political nature, Hayden was the son of the original settlers of what is now known as Phoenix, Arizona. The ferry his father built across the Salt River near modern Tempe, became the focus point for development of the modern city.
Where can we get Senators like this now?
Hayden kept a considerably lower national profile than conventional wisdom would suggest for someone who spent more than half a century in Washington, including 42 years in the Senate. This came in part due to advice he received from Maryland Congressman Fred Talbott soon after he arrived in Washington--"Son, there are two kinds of Congressmen—show horses and work horses. If you want to get your name in the papers, be a show horse. But if you want to gain the respect of your colleagues, don't do it. Be a work horse." Hayden quickly earned a reputation as a "service congressman" who faithfully responded to constituent mail, inserting vegetable or flower seed packets in his replies. Hayden believed that partisanship should end on election day, and his constituent service was performed in a nonpartisan manner.
