In April 1948, Dewey sent Paul Lockwood, one of his top aides, to build a strong grassroots organization in the state. Working with $150,000 sent by Dewey's powerful New York political organization (three times the previous record spent in an Oregon primary), Lockwood paid "for 126 billboards, hundreds of sixty-second radio spots on every station in the state, and half-hour broadcasts each noon...The daily "Portland Oregonian" carried five Dewey advertisements a day." Dewey also extensively campaigned in Oregon, spending three weeks in the state. He "invaded every hamlet, no matter how isolated, speaking at rural crossroads and shaking hands in hamburger stands. One journalist commented that Dewey was the greatest explorer of Oregon since Lewis and Clark."
