By this time, the first wave of what would eventually be more than four million letters, telegrams, postcards, and phone calls had flooded into RNC headquarters and other political offices. While a later study found that only about 7 percent of these communications addressed any substantive issue, they still ran 75 to one in favor of Nixon. Nixon skeptics joined in; both Stassen and Dewey sent congratulatory telegrams. Many letters included contributions to help pay for the cost of the broadcast; the RNC eventually recouped four-fifths of the $75,000 cost. Newspaper switchboards were jammed with calls from people seeking the RNC's address, while Western Union was caught off guard by Nixon's request that listeners wire the RNC, and had no extra help on hand. Checkers herself received enough dog food to last a year, and hundreds of collars, leashes, and toys.
