I don't think most people really give a fuck about abortion since only brainless cunts with no morality are ever in a position to need one. Its the same with gays. Most people vote half heartedly on those issues since they have no effect on their daily lives.
Main problem during an election would be big parties trying to force the discussion around useless issues like gays and abortion to vilify opponents. Hopefully the right wing opposition doesn't take any bait and keeps their answers short so they can't filibuster on such issues.
