“I know I have a responsibility if I am, as I hope to be, the Republican nominee for president, to unite the party and prepare for the great contest in November,’’ he said. “I am acutely aware that I cannot succeed in that endeavor, nor can our party prevail over the challenge we will face from either Senator Clinton or Senator Obama , without the support of dedicated conservatives whose convictions, creativity and energy have been indispensable to the success of our party that it has had over the last quarter century.’’ a speech Thursday to the Conservative Political Action Conference. -- cpac, john mccain
