Daniel, I'm afraid it's just inexperience / ignorance that makes me think that I was no longer dealing with a dictionary. I saw get() and went to the model in my mind. I looked at the source code for the forms module and it didn't seem that it was all of a sudden not a dictionary, and your response helps clarify the issue. Thank you very much for your help.
I was reading the doc page, "Form and field validation" and saw the difference in the two clean methods. It tripped me up for a bit, but I guess this different method of accessing clean_data makes good sense. It seems that clean_fieldname() will always return cleaned_data for all fields; if the field didn't pass validation it will still be returned as a python object, with the associated error(s). On the other hand, clean() for the form will only return fields in cleaned_data that have passed all their validation. One gets a hint of this from the documentation: "The clean() method for the Form class or subclass is always run. If that method raises a ValidationError, cleaned_data will be an empty dictionary. The previous paragraph means that if you are overriding Form.clean(), you should iterate through self.cleaned_data.items(), possibly considering the _errors dictionary attribute on the form as well. In this way, you will already know which fields have passed their individual validation requirements." I think this could have been a bit more explicit, but I might not have looked in the right spot for all the information. Thanks again, Daniel. Robin Ah!
