BD:
But I think the subjunctive in still in very good health in North America, especially after verbs like suggest, propose, recommend, ask, and related nouns and adjectives.
I googled: "suggest that he go" -462 hits
"suggest that he goes" -859 hits
"ask that he do" -193 hits
"ask that he does" -440 hits
"propose that he be" -170 hits
"propose that he is" -581 hits
Shall I continue?
Although I do think there is probably a correlation between the perceived sophistication (formality) of a verb and its demand for the subjunctive.
More common everyday verbs would command less subjunctive:
to ask
to demand
to desire
to insist
to suggest
to urge
While more "high-falutin" words would show more:
to advise
to command
to recommend
to request
Also one would expect to see more "Fossilized English Subjunctive" in writing than in everyday speech.
