Not sure what 'democratic process' you have in mind, since the current constitutional arrangements in Northern Ireland, as set out in the Good Friday Agreement, were approved by 71% in a referendum of the whole island of Ireland, north and south.
Yes, a Clinton production. Believe those numbers if you want. The only thing, IMO, the Irish wanted was peace between North and South - agreeing to the continued denial of independence in order to achieve that was the Clinton "deal." Nice bit of triangulation.
