In his own dealings as party leader, he was attentive to his subordinates and fair but firm. As Van Devander noted: "Jaeckle spends half of each week at home and during the rest of the time shuttles back and forth to New York City his headquarters famously was the Hotel Roosevelt on Madison Avenue at 45th Street, to Albany when the legislature is in session his headquarters was the Ten Eyck Hotel, and to other parts of the state. He is in frequent touch will all of the county chairmen, and succeeds in giving them the double impression that he is devoted to their individual interests, and that he is quite capable of breaking any one of them, politically, who might attempt to put anything over on him."
