I don't see why this question was deleted:
Do Ramsey idempotent ultrafilters exist?
It seems to be answered in comments. (Even though the answer was just link to a paper.)
And it might be of interest for other users.
I voted to undelete.
(BTW we don't have thread for undelete requests at meta - similar to the one for reopenings - do we?)
