Did the pollsters ask if the individual responded to the first poll? If they didn't respond, why? It seems like this type of information in the correct person's hands would allow the polling process to be fine-tuned and yield more accurate results for future runs.
Another bit of interesting information might be to have the user explain their choice of best product:
Fit company's need after analyzing competitors products.
No competitor products.
Did not make decision on selecting product.
Now, if the majority of your respondents are picking the last category, you know that you are missing the target you hoped to contact.
