OKLAHOMA CITY — Former Pennsylvania Sen. Rick Santorum criticized the failure of the “Obama-Clinton” foreign policy at the Southern Republican Leadership Conference, while saying the GOP needs to better connect with many voters who have given up hope.

Instead of focusing on answering questions about President George W. Bush’s handling of the Iraq war, Santorum said, Republicans need to focus on President Obama’s decision not to make a ‘real effort’ to defeat the Islamic State.
