Edited sentence: **It should be noted that since the Progressive Conservative Party merged with the Canadian Alliance to form the Conservative Party of Canada in 2004, the Progressive Conservative Senators all became Conservative Senators.In reality though, no such party exists at the Federal Level.The 5 Senators currently listed as "Progressive Conservatives" were appointed by the Liberal Prime Minister Paul Martin under this designation, over one year after the merger occurred.This was a political stunt aimed to draw a distinction between the former so called "progressive" party and the new Conservative Party
