(CNN)— Barack Obama came back from his vacation in St. Thomas Wednesday well rested and ready for battle. In the latest installment of CNN=Politics Daily, Suzanne Malveaux reports on Sen. Obama’s increased criticism of John McCain.

Meanwhile, John McCain continued his policy push, delivering a major speech on what he deems as his greatest strength over the Democratic candidates—foreign policy. CNN’s Dana Bash explains how McCain brought a personal touch to this serious subject.

Senior Political Analyst Bill Schneider has the details.
