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 reject the notion that government interventionism could save the country from the Depression.[230] 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.[231] Hoover's attempts to vindicate his administration fell on deaf ears, as much of the public blamed his administration for the depression.[232] In the electoral vote, Hoover lost 59–472, carrying six states.[233] Hoover won 39.7 percent of the popular vote, a plunge of 26 percentage points from his result in the 1928 election.
