Oh stop it. Santorum isn't going to change anyone's mind about contraception, whether porn should be legal, or whether women should stay home and have more babies. That ship has sailed, the issues have been settled. He is just going to cast himself as a guy who wants to argue about things that the public has largely put behind them.
He may be right about all those issues, but you have to pick and choose your battles. 2012 is not the time to re-argue the case for or against rubbers and birth control pills.
I am not personally a huge fan of universal suffrage. I do not necessarily think every person should have a right to vote. For one thing, anyone collecting freebies from the government should not be able to march off to the polls and vote themselves even more cash from the people actually producing something. Unfortunately, I am not going to win that fight anytime soon. I am in a minority opinion on this (even though I am convinced I am right and our nation would be much better off implementing my idea) and it would be flat out stupid to run on it as a campaign issue. I'd be flat out unelectable. Just as Santorum would be unelectable yammering on about how terrible contraception is. Now is not the time for that fight - especially with a president currently in office who will do anything he can to avoid talking about the economy because his stewardship of it has been so bad.
Stop what? Standing up against killing babies and destroying families? NEVER.
Despite your wild claims, Santorum is not running on banning contraceptives. You and your fellow libertarians/liberals are afraid to oppose him on the bigger issues of male-female marriage, drugs and abortion — because Santorum is within the Republican mainstream of those issues.
You insult social conservatives with your talk about settled issues. The institution of slavery was not a settled issue in the mid-1800s even though it had been around forever. Many times, peoples and nations have come to their senses and behaved better, through religious and political movements — not least to abolish slavery and stand up for the pro-life cause.
