No it's really not. You seem pretty reasonable. Please follow this line of reasoning: IF an individual's right to life is violated, NO OTHER RIGHT can be exercised. So we have no real liberty or rights if the right to life is removed.
IF the government is unwilling to protect the most innocent among them at all costs, then no matter what the FORM of government (or as you put it how it is organized) we hold it needs to be rejected!
Following on from your (also very reasonable) line of argument, see if you can follow mine
1) Although you might believe that the unborn individual's right to life is more important than a form of government, I'm sure I can (and probably you can) conceive of a form of government with which you would be unhappy in any circumstances. I would certainly be unhappy with any form of government which did away with the ability of the electorate to remove that government, because although the present "benevolent dictator" did all the things we want, we don't know what the next one will do. I'm only trying to show here that the form of government is important and needs to be taken into consideration, and so the answer is not black and white on this issue.
2) The means by which you suggest the individual's right to life is restored can easily be overturned by the same method, unless on the way it achieves some kind of consensus.
3) Abortion is a very contentious issue. It seems to me that the more hard line someone appears on it, the more difficult it is going to be for them to get the widespread general support they would need to win a presidential election. If they did go all out and win, and then go on to make such wholesale changes, it's quite possible for their successor to win the next election purely on the back of overturning what their predecessor did (see point 2).
I believe the correct way forward is to try to depolarise the issue. People who are pro-life stereotype those who are not as being murderers. People who are pro-choice stereotype those who are not as wanting to infringe a woman's right to do what she wants to with her body.
In fact, neither of these stereotypes are true. Pro-choice people do not believe (generally) that murder is a good thing, pro-life people don't (usually) want to remove the rights of the individual. The whole argument only hinges on where you believe life starts, and where you believe human rights start and finishes.
I believe that's why these sorts of debate are better done out of the glare of a high profile election.
