HARRISBURG, Pa. (AP) — Pennsylvania's 72 delegates are on their way to — or already in — Tampa, Fla., in preparation for Monday's opening of the Republican National Convention.

Random telephone interviews by The Associated Press with more than a dozen of the 72 delegates confirmed abundant enthusiasm over the Romney-Ryan ticket's prospects in the Nov. 6 presidential election.

Yet some delegates say presidential nominee-apparent Mitt Romney needs to better explain his agenda and fighting the perception that he is out of touch with middle-class voters if he expects to win a swing state like Pennsylvania.

State GOP chairman Rob Gleason calls it the most important speech Romney will make in his life. Gleason says Romney needs to lay out his "blueprint for America."
