The liberal leadership race does seem low on the current radar of many.

Personally, I see the benefits of a multi party government, versus a two party one (for example, as in the USA).

It makes it more interesting, and provides an opportunity for new ideas to hatch and sometimes grow. There are good examples of third parties having an influence on governing party policies, for example, Tommy Douglas' influence on the earlier Trudeau.

I am not eager to see Canada's political scene evolve into a two party scenario (I admit there are also minor parties, but most have had minimal influence, beyond local issues - Block and Green- and with some media).
