The Liberal Party is a Progressive party, whereas the Progressive Conservativ party is a Conservative party. This  is how the electorate views the two parties, and if the electorate is primarily progressive, then there is really only one progressive party. The PC party is flying a false flag, and needs badly to emulate the federal name change and fly a conservative flag in Ontario. After all, that worked for the federal party. As for the progressive faction in the PC party, they are less conservative and more liberal, and so there is conflict within the party, and the name itself can but confuse the elector who sees opposite meaning in the words progressive and conservative. This confusion in the minds of the PC members has helped the party lose elections to the Ontario Liberals, and may well do so next time. So it's time for a name change.
