Link: The Canadian Press A popular Canadian TV comedian went rogue at a Sarah Palin book-signing in Columbus, Ohio, on Friday, confronting Palin with a tongue-in-cheek question about the Canadian health system. "We told her we're from Canada, and we're just looking for a few words of encouragement for the Canadian conservatives who have worked so tirelessly to destroy the socialized medicare that we have," recalled Mary Walsh of the CBC show "This Hour Has 22 Minutes." Security guards removed Walsh from the area, but she was able to confront Palin again after the signing. Palin told Walsh and her crew that "Canada needs to reform its public health care system and let the private sector take over." Watch video of the exchange here. Canada has a broadly popular single-payer health care system, under which all residents are covered and the government reimburses doctors for almost all medical services they provide. Palin has regularly voiced opposition to health care bills before Congress that would expand insurance coverage for Americans.
