text_A: Hoover originally planned to make only one or two major speeches, and to leave the rest of the campaigning to proxies, as sitting presidents had traditionally done. However, encouraged by Republican pleas and outraged by Democratic claims, Hoover entered the public fray. In his nine major radio addresses Hoover primarily defended his administration and his philosophy of government, urging voters to hold to the "foundations of experience" and embrace the notion that government interventionism could save the country from the Depression. In his campaign trips around the country, Hoover was faced with perhaps the most hostile crowds ever seen by a sitting president. Besides having his train and motorcades pelted with eggs and rotten fruit, he was often heckled while speaking, and on several occasions, the Secret Service halted attempts to hurt Hoover, including capturing one man nearing Hoover carrying sticks of dynamite, and another already having removed several spikes from the rails in front of the president's train.
text_B: Were the "foundations of experience" probably similar to the idea of government intervention with regard to dealing with the Depression?
YES.
