For me the most interesting outcome of the 19 Oct 15 election will be the fate of the leaders. Assuming the current polls are fairly accurate and will hold up for four more weeks, and there are none of the
"events, dear boy, events" that used to worry British prime Minister Sir Harold MacMillan (later 1st Earl of Stockton), then a minority seems most likely, probably either an NDP minority (50
ish% likelihood), or, (40
ish%) a CPC minority or, less likely (maybe 10%) a Liberal one.
I think Prime Minister Harper is toast, even if he wins and even if (thanks to some unforeseen
"events") he won a majority. If he wins he will be the toast (pun intended) of his party and the political establishment for being the first PM since Pierre Trudeau to have won four mandates,*
but it will not last: he is too unpopular and, by rights, his party should have rebelled, as the Australian Liberals just did, last year.
I believe that, again absent those pesky
"events", M Mulcair is secure in his leadership.
That leaves M Trudeau.
If he wins then he is, of course, secure ... just how secure will be a function of how well he wins and what happens in the following election, but Liberals do not jettison winners.
If he finishes second there may be some questions, but
my guess is that he will still be secure.
What happens if he finishes third, as the polling still suggests he will? (He might beat the CPC in the popular vote but
vote efficiency could condemn the Liberals to third party status.) In that case
I suspect that even if he makes a major
improvement to the Liberal Party's fortunes, in terms of seats won, his leadership will be challenged. The Liberal;s have some young, but seasoned, MPs just waiting to do better and there are some fresh new faces on the horizon ...
Andrew Leslie and
Catherine McKenna, both here in Ottawa, just to name two. Many Liberals, MPs and party activists will be dismayed if the party does not achieve official opposition status at the very least.
