The Partial Birth Abortion Ban was enacted in 2003 and upheld by SCOTUS in 2007, yet it has done NOTHING to stop late-term abortions even though Pro-Life, Inc. went out of their way to praise themselves for it. Today, instead of inducing labor to kill the baby, the abortionist injects potassium chloride or digoxin into the baby's heart to kill it and it's completely legal.
Even Rick Santorum supported Arlen Specter for president, on a campaign to end the GOP as an anti-abortion party, and Santorum supported him even for the 2010 election.
Romney was a serious threat to the GOP platform on life, and so is Rand Paul.
