1. The problem asks for the number of respondents who were not Democrats and did not think he was doing better. 2. To solve this, we need to understand the categories: "not Democrats" and "did not think he was doing better". 3. Usually, survey data is organized in a contingency table or Venn diagram format. The respondents can be divided into Democrats and non-Democrats, and also into those who think he is doing better and those who do not. 4. The number of respondents who are not Democrats and did not think he was doing better corresponds to the intersection of these two groups. 5. Since the problem does not provide explicit numbers or percentages, we cannot calculate an exact number without additional data. 6. If you provide the total number of respondents, the number of Democrats, and the number who think he is doing better, we can use the formula: $$\text{Non-Democrats and not thinking better} = \text{Total} - \text{Democrats} - \text{Those thinking better} + \text{Democrats thinking better}$$ 7. Please provide the missing data to proceed with the calculation.
