Process a pandas Series of text data by lowercasing all letters, removing non-alphanumeric characters (except spaces), removing punctuation, and stemming each word to its root form. Stemming is done using the NLTK's PorterStemmer, which applies a series of rules to find the stem of each word.
The function should output with:
    pandas.Series: A Series where each string has been processed to remove non-alphanumeric characters,
    punctuation, converted to lowercase, and where each word has been stemmed.
You should write self-contained code starting with:
