As leader, Harper was instrumental in instigating a merger between the CA and his old rivals, the Progressive Conservative Party, which was now led by [[Peter MacKay]], a man who was open to the idea of joining forces to help "unite the right" in Canada, and create a party powerful enough to defeat the entrenched [[Liberal Party of Canada]]. Harper's eagerness to merge led him to compromise several key principles of the Canadian Alliance, however. In order to win the moderate MacKay's support, Harper "softened" many of the CA's positions on issues. | As leader, Harper was instrumental in instigating a merger between the CA and his old rivals, the Progressive Conservative Party, which was now led by [[Peter MacKay]], a man who was open to the idea of joining forces to help "unite the right" in Canada, and create a party powerful enough to defeat the entrenched [[Liberal Party of Canada]].
