AssassinatedBeauty, to answer your question about "health risk", I'm not sure that people (in general) see pregnancy as being risky any more.
I personally am against allowing abortion in the case of suicide ideation, rape or any other very restricted system, simply because I don't want to see women, and especially teenage girls, have to prove they "need" an abortion. The original suggestion of abortion in cases of suicide risk had the suggestion of girls having to appear in front of a panel of doctors who would decide; similarly for rape, the girl would have had to declare in front of experts she had been raped. Neither are provable, and both are open to abuse (in that girls could be forced to say they were suicidal, or had been raped, in order to get an abortion).
I'm using "girl" here because if we are honest about it most older women who need an abortion will travel for one; the people being prevented here are the young, the poor, the uneducated, the unsupported.
I think the current suggested "on demand to 12 weeks" is the best we can hope for at the moment.
But listening to the person in charge of the Red Sea polls, and how they are trying to word the questions different ways to get an accurate result, is very upsetting. They have come to the conclusion that people don't answer honestly in opinion polls, that people who are intending to vote no won't admit it. So, in their opinion, "undecided" means "no" - which has always been my fear.
The most recent polls have the yes side at 52 to 56%. Every one of those people will need to turn out and vote, because it's likely the 27%ish No's will be joined by the 20%ish Don't Know's - and they will be brought to the polling booths by the busload.
The no campaign (judging by the posters, the campaigners, the numbers on the streets and the willingness to transport older people around on Friday) seem to have unlimited resources.
In Ireland there is still the niggling feeling among many that abortion is wrong - I'm worried that many will panic at the last minute and not vote, or decide at the last minute that they can't bring themselves to do so and it will be lost 
It's 35 years since I first voted on this; if we lose this time, I'm not sure we'll see another referendum in my lifetime.
