William Jennings Bryan used a nationwide speaking tour and the phonograph to campaign in ways that had not been done before in American politics.
Step-by-step explanation:
In his campaign, Bryan utilized a number of tactics that had not been done before in American politics. One of the most significant was his use of a nationwide speaking tour. Bryan traveled across the country, delivering powerful speeches that resonated with ordinary citizens. This was a new approach at the time, as previous campaigns had primarily relied on local rallies and events. Additionally, Bryan utilized the relatively new technology of the phonograph to record his speeches and distribute them to a wider audience. This allowed his message to reach people who were unable to attend his speeches in person.
