The head of Canada’s Liberal Party has decreed that all new candidates running for parliament in his party–or is it running for any office? that part isn’t clear to me–must be pro-abortion. The socialist New Democratic party has a similar policy. The Conservatives will allow pro-lifers to run for office, but they are not allowed to bring up the issue.
Thus all major Canadian political parties–there are some smaller ones that pro-lifers can presumably join–are working together to exclude the pro-life cause from political consideration. Think something like that could happen in the USA?
