Some pro-lifers believe that proportional representation will result in the appointment of Family Coalition Party members at the provincial level and Christian Heritage Party candidates at the federal level. Sadly, neither party has reached the minimum 3% level of province-wide support that most proportional representation systems require to garner seats in parliament. Until there is a sea change in their support, the number of FCP/CHP elected officials would be negligible to effect change.One may add that the threshold was set to 3% precisely because no small party was able to get that many votes in decades. We know that the Green Party of Ontario came quite close to 3% in the past election. But not many remember that Family Coalition Party too came very close to a 3% threshold, winning 2.76% of the vote in the 1990 election.(Source)
People voted FCP despite the perception that it draws votes away from the PC and makes it easier for a Liberal or NDP candidate to win the riding. There were only 68 FCP candidates running in the 1990 election, thus nearly half of Ontario voters (those in the remaining 62 ridings) didn't even have a Family Coalition Party candidate on the ballot. Yet FCP still won over 110,000 votes.
If the Mixed-Member Proportional system had been used back then; if the Family Coalition Party name had been listed on each ballot among with other parties; if the voters had been able to make their choice without worrying about vote splitting, those numbers could have doubled. Winning 220,000 - 250,000 votes (5.5% to 6% province-wide) would have entitled FCP to 7 or 8 seats. Even if it hadn't been enough seats for the official party status, it would have been enough voices to make a difference in a minority Parliament.
Yes, since 1990 many FCP supporters chose to vote strategically. Even in the 2003 election many of them still considered the Progressive Conservatives to be far lesser evil than the Liberals. But now, when John Tory's leadership made the Ontario PCs virtually indistinguishable from the Liberals (not just socially but also fiscally) and with the left of centre vote being split three ways (Liberals, NDP, Green), I won't be surprised if at least one of the FCP candidates manages to win a local seat in this upcoming election.
