Romney says he still expects to be GOP nominee

DENVER — 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.

Romney, speaking from Denver on Tuesday night, focused his speech on Obama, who accepted the Democratic nomination for president in Denver in 2008.

Romney says Obama has failed to make good on his promises, especially in his pledges on economic policy.
