Mitt Romney says it's been a good night for Rick Santorum, but that he still expects to become the Republican nominee for president. After losses to Santorum in Missouri's non-binding primary and the Minnesota caucuses -- where he is in third place -- Romney is congratulating the former Pennsylvania senator but continuing to focus on President Barack Obama. Despite Tuesday's setbacks, Romney says he is ready to lead the Republican Party and is happy to compare his record on leadership to Obama's.
