Week 1 projection map |
Last Friday, Ontario NDP leader Andrea
Horwath announced that she would no longer be supporting the governing
Ontario Liberal Party's budget. This triggered Premier Kathleen Wynne to call an
election for the province which will be held on June 13. Officially,
the writs will drop on Wednesday, and the campaign will officially begin.
The Liberals have governed the province
since 2003, and have been led by Premier Wynne since February 2013
when provincial Liberals elected her leader, replacing the previous
leader Premier Dalton McGuinty, who had resigned. Since the last election held in 2011, the Liberals have faced many scandals, such as the “gas plant scandal”. The scandals, as well as a number of corruption controversies threaten their
11-year reign. In the last election held, voters returned a
Liberal minority government, with the Liberals winning just one seat shy of a
majority. However, subsequent by-election losses have eaten into this
minority. Since 2011, the Liberals have counted on the support of the
left wing NDP to help keep the government going. On Friday though,
the NDP had enough of the scandals and alleged corruption and
withdrew their support. The opposition Tories, led by Tim Hudak, have
not supported the Liberals since the election. In recent polls, the
Progressive Conservatives have traded with the Liberals for the lead among Ontario voters. Up
to about a year ago, they consistently led in the polls. Since the
last election, the NDP have also polled quite well, compared to their
historic third place showings. They even led in one poll conducted in
January 2013. Just in the last two weeks however, the NDP have fallen
back to their 2011 election numbers in the low 20s.
The beginning of a provincial election
campaign means that once again I will attempt to do weekly
projections of what the polls are showing, and then map the results
to predict what might happen on election day. For my first
projection, I will be using two recent polls conducted by EKOS and
Forum Research. The EKOS poll released on May 2, showed the Liberals
in the lead with 34.7%, the Tories in second at 31.6%, the NDP at
22.2% and 9.4% for the Greens. Forum Research released a poll the
next day showing very different numbers. They have the Tories at 38%,
the Liberals at 33%, the NDP at 22% and the Greens at 6%. What this
means is that the Liberals and Tories are in a statistical tie at the
moment, and the parties are close to where they were at in the last
election.
Pumping the regional numbers from both
polls into my new Ontario election model, I get a very narrow PC
lead, with the Tories at 46 seats, the Liberals at 43 and the NDP at
18. This would result in a minority Progressive Conservative
government in the 107 seat legislature.
Methodology
The basis of my
model extrapolates the results of the 2011 election using regional
polling averages from recent polls. If a party is polling at double
the level they won in 2011, then that party would see its support
double in each riding in the region my model. I have also taken into
account recent by-elections, but projecting the results of the
by-elections backward to the last election based on poll numbers from
around the time of each by-election. That is, if a party did 5 points
better than polls indicated they would've won in a by-election, then
I have made their 2011 result 5 points more than they actually
received in 2011. (I've only done this for the NDP, the PCs and the
Liberals, except for Thornhill where I only did it for the PCs and
Liberals).
In the coming
weeks, I will be doing further tweaks to my model based on a number
of factors, such as candidate strengths. However, candidates are
still being nominated, so they have been ignored for the time being.
You can say that this model reflects polling data as if all
candidates were the same as in 2011 (or recent by-elections).
Odd results
I should also
mention some strange results in my model that I hope will be
corrected before my final projection on election day. Ontario,
being my hope province, is the province that I know the most about in
terms of its political geography. I like to think that I have a good
knowledge of how ridings will vote, even without a model helping me.
In 2011, without the aid of a true mathematical model, I correctly
predicted the winner of 92% of the ridings. (threehundredeight.com
which did use a mathematical model only correctly projected 85% of
the ridings). This knowledge will allow me to identify any flaws in
my model so that I can come up with “tweaks” to correct them. In
this first map, the three strangest results in my opinion are:
* Barrie. My model
has the Liberals ahead here thanks to the EKOS poll showing the
Liberals ahead in the 705 area code. However, I think the Tories will
easily win the seat. The seat is currently held by the Tories, and in
the 2011 federal election, the Liberals won just 16% of the vote. In the last
election, the race was close, so any strength the Liberals have in
the 705 is going to give Barrie to the Liberals in my model. The
Liberals haven't nominated a candidate yet, so they don't seem to be
prepared to win this one.
*
Scarborough—Guildwood. My model has the Tories ahead, thanks to a
close by-election result from last August. However, I believe the
Liberals will win it. The candidates for both the PCs and the
Liberals will be the same as in the by-election, but the wild card is
the NDP. In the by-election, the NDP ran city councillor Adam Giambrone who was popular
enough to eat into Liberal support in the riding. The NDP have yet to
nominate a candidate, and are unlikely to nominate anyone of
Giambrone's strength, so Liberal support is likely to go back up to
normal levels. This riding has a Liberal history, and is one of the
few ridings the federal Liberals were able to win in the 2011
election. I don't see the Tories winning any seats that their federal
counterparts didn't win in the last federal election.
* Kenora-Rainy
River. Small sample sizes in the 807 area code from the EKOS poll,
and strong Tory strength in Forum Research's “Northern Ontario”
region (which likely takes in all of the 705 area code which includes
large swaths of Tory friendly Central Ontario) are to blame here.
Currently, my model shows the PCs ahead in this riding, but its
history clearly indicates the riding will likely be won by the NDP.
When the NDP won the riding in 2011, it came as somewhat of a
surprise to me, as I predicted the Tories would win. After all, the
riding overlaps with the federal riding of Kenora which the NDP have
failed to take back from the Conservatives in recent elections.
However, the NDP ran a strong candidate in Sarah Campbell, who had
worked for the riding's previous MPP, former Ontario NDP leader
Howard Hampton. Hampton had represented the area since 1987. I
suppose the Tories could win it, but it will be a bit of a long shot.
Gains and losses
Compared to the 2011 election, my model shows the Tories picking up 11 seats: Etobicoke-Lakeshore, Scarborough-Guildwood, York Centre, Brant, Kitchener Centre, Glengarry-Prescott-Russell, Ottawa-Orleans, Ottawa South, Ottawa West-Nepean and Niagara Falls (from the Liberals) and Kenora-Rainy River (from the NDP). It has the Liberals picking up two seats: Trinity-Spadina (from the NDP) and Barrie (from the Tories), and it has the NDP picking up three seats: Kitchener-Waterloo (from the Tories) and London West and Windsor-Tecumseh (from the Liberals). The Tories would have a net gain of nine seats, the NDP would have a net gain of one seat while the Liberals would have a net loss of 10 seats. Some of these changes aren't really gains or losses due to recent by-elections (like in Etobicoke-Lakeshore, Kitchener-Waterloo, Windsor-Tecumseh and London West, while in Niagara Falls, the Tory gain is actually from the NDP who won the riding in a recent by-election)
As always, I will be taking in
suggestions from readers about ways I can improve my model. So please
share with me your opinions. I will also be monitoring electionprediction.org
to see what submitters to that site think about how each riding will
go.
Here are my projected numbers for each
seat. Ridings are coloured by how they voted in 2011.
"This would result in a minority Progressive Conservative government in the 107 seat legislature"?? Come now, you know better than that.

You're right, I do know better than that. Perhaps I'll be more careful with my wording next time.
