I'm as peeved about the Stupak amendment as anyone else, but with the paranoid political climate out there, I expected nothing else. It makes me wonder why I've never seen supplementary coverage for abortion available for sale. There is the self-selection thing, where people philosophically opposed to abortion wouldn't buy a policy, but the procedure itself usually isn't very expensive, so I imagine a pool of pro-choice policy-holders who may never find themselves needing to access their abortion coverage would be able to support the cost of the procedures undertaken.
I'm at a stage in my life where if a pregnancy comes, I'll go with it, but a D&C is something even some planned pregnancies end with, so I couldn't honestly skip buying a cheapish policy out of self-interest. Then again, the cost of a simple abortion is probably the kind of cash I could scare up at a time when I needed it, so I would be a lot better off just donating to an abortion fund, rather than building a policy where some of my money would have to be skimmed off the top of the pool to line the pockets of some insurance broker.
Maintaining access to abortion is something that a not-explicitly-feminist organization can't really do at the moment, so as always, it's up to the explicitly feminist organizations to make it happen.
