Perhaps a better version: IF KILLING YOUR OWN UNBORN CHILD IS YOUR MOST IMPORTANT ISSUE, YOU SHOULD VOTE FOR DEMOCRATS, IF YOU WANT A BETTER FUTURE FOR YOURSELF AND YOUR CHILDREN, THEN YOU SHOULD NOT

I don't want to say "vote for Republicans", because there may be non-Republicans in a race, and as far as I can tell, almost without exception, any non-Democrat is always better than any Democrat. It also leaves the option of them not voting for anyone :)
