this is walter cronkite in miami beach at this first session of the republican national convention. >> richard nixon was the leader. but he walked into the republican convention not positive that he would be the candidate. >> the new-fashioned nixon runs an old-fashioned campaign. and that's what the country seems to want. >> there were challengers. there was nelson rockefeller in new york, for starters, and george romney in michigan. there was some talk of reagan. but nixon had a lock on the delegates.
