Explaining interim leader's not running for leader 

Homey has removed, first because it was "obvious" and then because Graham isn't listed as a potential candidate, the paragraph that explains why Graham cannot, by convention, run for leader while serving as interim leader.  As pointed out above on the talk page by a non-Canadian reader, this is something that should be included because in other countries, most notably in Britian with recent election of Robert Menzies as leader of the Liberal Democtats, interim leaders can, and often do, run for the leadership.  I will re-add this paragraph for these reasons. -
