Conservative platform a blueprint with a centrist touch

In this article from the Globe and Mail, the journalist discusses what came about from the Throne speech that was held yesterday and what the Conservative platform entails.

While there is chance for a federal election to be called in the near future, the Conservatives feel that delaying the dropping of the election writ may be beneficial for them. A new Strategic Counsel poll suggests that the Conservative government does not have enough support for a majority government, which is obviously the Conservatives ultimate goal.

Based on the Conservative platform, the plan is to hug the moderate middle of the political spectrum. A political science professor states that this is a "long-term plan. The right would be reorganized as the centre-right, which displaces the Liberals. And the NDP, if the Liberals are weak enough, can move slightly more to the centre-left." Therefore it appears that Harper's ultimate objective is the annihilation of the Liberal Party.
I do not like this idea of the right becoming more central, and the left moving to be more central as well. I believe that the idea of having 3 different political parties, ranging from the right, to left - with a party in-between is beneficial for Canadian politics and for democracy. Although the parties can be seen to be quite similar, there is still some variance in policies and allows citizens to vote for the party/leader that best fits their own individual ideologies. If there is a convergence of political parties to become even more moderate, there is less choice for citizens to make on how they want the government to run the country.
After reading the summary of the Throne speech and the vows the Conservative government has made illustrates the fact that the right is moving more to the centre of the spectrum. One positive of this approach is that if the Conservative government gets re-elected when there is a federal election, left-leaning policies may have more of a chance at being recognized at the federal level.
