The computer letter, asking for immediate and future contributions, had four blank checks, a mailing label addressed to the recipient, and an application for a button identifying the wearer as an early McGovern supporter. particular attention. Such donor lists can bring a response from between 10 and 25 percent of the addressees. Governor George Wallace of Alabama has virtually perfected this technique, raising millions of dollars in small contributions from "just folks" over the years. But no major fund raising effort can be a folksy, backroom operation. It must be highly sophisticated, with computerized letters-perhaps mentioning the recipient by name in the body of the letter, perhaps not-going to lists of special interest voters, who usually get a basic letter with variant paragraphs for different groups. Such an endeavor might also include an information storage system retaining the names of contributors and the amounts they contribute, and capable of purging those who prove unresponsive after a few tries. Perhaps the greatest computerized fund raising coup was the brainchild of Thomas L. Collins of the New York advertising firm of Rapp, Collins, Stone and Adler. During the 1972 presidential election Collins sent out a mailing on behalf of Senator George McGovern (for obvious reasons candidates with a strong ideological identification do best in this sort of drive) to a prime list of past and potential contributors at a cost of $25,000. The computer letter, asking for immediate and future contributions, had four blank checks, a mailing label addressed to the recipient, and an application for a button identifying the wearer as an early McGovern supporter. Americans, it seems, don't like to take something-not even a campaign button-for nothing, because 100,000 donors sent in $1 million in response to this mailing. Polling Polling: With enough money a campaign can go in any direction its directors choose; the problem is in defining the direction that will be most effective. The computer and its legitimate offspring, the poll, are there to help answer this all important preliminary question. The kinds of polls available are about as many as the number of campaigns in which they have been used. Most depend on random samples of 100 or more names, below which the data is most suitable, culled from census lists, the telephone book, random digit dialing, or from any predefined list. The sample is screened to weed out the noncitizen, the unregistered and the non-voter. From there the pollster will frame questions designed to tell his client what he wants or needs to know. A few examples should suffice: Asking preliminary demographic questions can yield a profile of the electorate's characteristics. Asking whether the respondent will vote in the forthcoming election can yield a maximum likely turnout. Collating the results of these two questions can yield a profile of likely voters, indicating not only how many people will vote but also what kind of people will vote. Asking the respondent's predisposition toward the candidates can yield a model of the undecided voters similar to the model for all probable voters. Richard M. Hochhauser, a former vice president of Cambridge-Plesser, a research opinion consulting firm, and now president of RMH Research, Inc., outlines the six basic kinds of political polls, any combination of which may be used in an individual campaign. 1. An Issue Definition Poll seeks to ascertain what the electorate at large and/or some portion of it (the most likely voters, various age groups, various religions or ethnic groups, probable supporters or opponents, etc.) sees as the most serious problems facing the city, state or nation. The pollster can gather the necessary data either by asking relevant questions directly or by providing a list of issues and asking the respondent to rank them. 2. A Bench Mark Poll, conducted with as much as a year's lead time, provides the information with which to screen the electorate, classify the voters demographically, develop a media profile (i.e., establish what the voters read and watch), determine the degree of the candidate's name recognition and the public's knowledge of him, evaluate the public's image and opinion of the candidate, establish the importance of the forthcoming election, and measure the depth of conviction of committed voters and the importance of party identification. With this information at hand a prospective candidate has the wherewithal to decide whether to go ahead with his campaign and, if so, what kind of pose to strike and what kind of campaign to run. 3. A Tracking Poll updates the information in a bench mark poll sometime before election day. Since much of the cost of polling is devoured by actual interviewing time, the use of the same sample as in the bench mark poll can save a campaign considerable money. 4. A Target Voter Survey selects a sample of voters whom the campaign wishes especially to reach. It may try to measure penetration into the opposition's supporters, or the degree of the campaign's effect on undecided voters or on some other subdivision of the total electorate. 5. There are two kinds of Communications Surveys. One, the Theme Effectiveness Survey, is used to determine the kinds of ads a campaign should use. There may be three possible ways of reelecting an aging incumbent, three thematic hooks on which to hang the entire campaign: "Senator Smith, a man of experience and accomplishment," "Senator Smith's stand on the issues," or "Youth can't keep up with the activities of Senator Smith." A theme effectiveness survey can help decide which would be most persuasive. The other, an Ad Effectiveness Survey, is used to determine the ability of specific ads, already released, to accomplish their desired effect. Obviously ads may have different impacts on different elements in a constituency, so a communications survey employs various screening questions to measure an ad's effectiveness with specific groups of voters. Furthermore, voters in different media markets may react differently. To take these differences into account in statewide or nationwide elections, the same poll is often conducted separately in each relevant media market. (Earlier polls may also be duplicated in as many media markets as funds allow.) 6. The last type of poll is the one candidates, campaign managers, and consultants like to conduct least, the Post Mortem Survey, which seeks to discover why the candidate lost. Actually, such polls are not always lamentable events. Often they are a part of the process of planning for ultimate victory, a process which sometimes extends over more than one term. Voter Identification Voter Identification: Hochhauser and those like him deal primarily with categories of voters, generalizations extrapolated from interviews with individuals. But there is another way of looking at voters, other categories of voters with which candidates and campaign managers must deal. These classifications define voters in a way that allows dealing with them specifically and individually rather than generally. One such division is party registration, which is part of the public record and readily available at any Board of
