perhaps the most obvious tranformation in political campaigns has been in the area of technology.although the additions of radio in the 1920s and televistion in the 1950s brought with them a number of alteration to us political campaigns, as technological advancements, they were only the beginning. today, campaigns from the country to the national level rely on a number of devices sophisticated enough to have hardly even been envisioned in a campaign as contemporary as jimmy carter's in 1976. in so doing,their nature as well as the people who run them have changed.for example, in statewide as well as president campaign, the old electoral map on the headquarters wall showing in what districts the voters live has been supplemented with a map of the major media markets.
