British Columbians head to the polls
next month (May 14) to elect a new government. In the past, I have
made provincial election predictions, but unfortunately due to my new
position at Probit Inc. I
will be holding off on making predictions, due to possible conflict
of interest purposes. However, I will be making various geography
related posts in having to do with the upcoming election, including
projections based
solely on published polls, without factoring in any hearsay like I
have done in the past.
Today,
I take a look at the B.C. “swing-o-metre”, a simple measurement
tool that shows how much swing is needed for the Liberals or the NDP
(B.Cs two main parties) to win a seat. A swing
is
a calculation that is the average change between the Liberals and the
NDP. For example, the most recent Ipsos-Reid poll shows the NDP at
48% and the Liberals at 29%.
For
the NDP, that would be an increase of 6% from their showing in the
last election in 2009. For the Liberals, that would be a decrease of
17%. If you average those two numbers you get about 11.5%, which
would be the swing
from
the Liberals to the NDP.
The
chart on the left shows the swing needed for either party to win each
seat from the result they got in the last election. For example, for
the Liberals to win the riding of Surrey-Green Timbers, they would
need a 24% swing from the NDP. On the other extreme is the riding of
West Vancouver-Capilano which would require a 26% swing from the
Liberals to the NDP in order for the NDP to take the riding. This
swing-o-metre works because all but one seat in the legislature was
won by either party in 2009. One riding, Delta South was won by an
independent, however I kept that riding on the chart to show how much
the NDP would need in order to get ahead of the Liberals there (but
not necessarily win).
In
the 2009 election, the conservative leaning BC Liberals, lead by then
Premier Gordon Campbell won a majority of the province's 85 ridings
by winning 48 seats to the N.D.P.'s 35. (As mentioned, 1 seat was won
by an Independent). Since then, Campbell's government became very
unpopular, and he resigned. He was replaced by Christy Clark, who as
of yet has been unable to rescue the party. During her reign, the
province has seen the rise of the even more right wing Conservative
Party, which had been a fringe party. It is now lead by former MP
John Cummins. While the new Conservatives may not win any seats, they
are polling in the low teens, and that vote is coming straight from
the Liberals. However, even if the Liberals and the Conservatives
were a united force, they still wouldn't match the polling the NDP is
at. The NDP is at historic highs in the polls, led by popular leader
Adrian Dix. Most polls show the NDP in the mid-40s, and the Liberals
in the high 20s. There is also the BC Green Party, which is polling
around the level of the Conservatives.
The
most recent polls, from last week show a 7-12% swing from the
Liberals to the NDP from the last election. According to the
swing-o-metre, this would give the NDP 55-65 seats, a strong
majority. The swing-o-metre also shows that the NDP needs only a
swing of 1.93% to get a majority of the seats (43). This swing would
give them the ridings of Maple Ridge-Mission, Cariboo-Chilcotin,
Saanich North and the Islands, Oak Bay-Gordon Head, Kamloops-North
Thompson, Burnaby North, Burnaby-Lougheed and Vancouver-Fraserview.
To get to those 55 seats, the NDP would also win Vernon-Monashee,
Surrey-Tynehead, Vancouver-Point Grey (Premier Clark's riding), North
Vancouver-Lonsdale, Chilliwack, Port Moody-Coquitlam (a riding they
hold now, thanks to a by-election win last Spring), Penticton, Prince
George-Valemount and Parksville-Qualicum (securing a sweep of
Vancouver Island). Of course, this only assumes a province-wide
uniform swing, which we know wont actually happen. But it's a rough
guide to see what riding's are in play.
