It's like "I've voted Fianna Fail all my life and thats the way I'm always going to vote!" It's bloody irresponsible.
More like pragmatic. The political historians may differ over who laid the seeds which made the unprecedented econonic boom we have witnessed this last 15 yeara - all the voting public knows is that Fianna Fail have presided over most of it - steering (in so far as they can have steered it) a successful course. "Its the economy stoopid" Any one who lived in the years prior to this period remembers what a miserable place it was.
If it ain't broke don't fix it. Its not like there is much in the way of percieved choice anyway.
Remember too with regard to referenda. If the government wants us to vote it in, they are prepared to bully, threaten, cajole and if that doesn't work then they'll polish it up, remove the objectionable frills and present it again to us a few short months later
Gay rights doesn't strike me as something any Fianna Fail government would see as beneficial to retention of power. Why risk it?
