I think the first step would be to use a tool for word selection that does a better job finding actual synonyms instead of "words that are vaguely the same".

The phoneme matching aspect of it obviously works very well. I think if you had more control over the words it would use, you'd get better results. See my comment about "politician" above. I've repeated tried combinations with the word politician in them, and none of the synonyms I would expect to show up ever showed up.
