Harper considered campaigning for the Progressive Conservative Party leadership in 1998, after Jean Charest left federal politics. Among those encouraging his candidacy were senior aides to Ontario Premier Mike Harris, including Tony Clement and Tom Long. He eventually decided against running, arguing that it would "burn bridges to those Reformers with whom I worked for many years" and prevent an alliance of right-wing parties from taking shape. Harper was sceptical about the Reform Party's United Alternative initiative in 1999, arguing that it would serve to consolidate Manning's hold on the party leadership. He also expressed concern that the UA would dilute Reform's ideological focus.
