The premise is that in key ridings opposition parties only run one opposition candidate. Then immediately after the election, electoral reform is put in place to stop the perverse election outcome from happening again.
Cooperation is harder than it looks
There are a few problems with this approach. For one, it would be difficult, if not impossible, for parties to agree on which party runs a candidate in which riding.
Second, the media would call this move “undemocratic” because it takes away the choice of voters.
Third, Canadians are divided on the kind of electoral reform they support.
Odds are electoral cooperation won’t be needed to stop Harper in 2015. Voters will be begging for change by then. If Harper doesn’t win a majority, opposition parties are going to oust him with some form of alternative government.
The real problem is what comes after. Since minority governments don’t last long, the Cons could be back in power for another decade as soon as 2017.
Instead of parties deciding which candidate to run, voters decide which center-left candidate they like best by ranking choices. This allows one to vote “Anyone But Conservative.”
Since this stops vote splitting, the Cons will never again get their hands on center-left ridings.
Progressive voting reform
What’s best is that this would cut corrupt First-Past-the-Post out of the picture — only democratic voting systems would be on the table.
