Leukemia patient Julie Boonstra is the latest American to get caught up in the media fact-checking frenzy. Her offense: Appearing in an anti-Obamacare ad for Americans for Prosperity, in which she said her out-of-pocket costs had become “unaffordable” since her insurance was canceled because of President Obama‘s health care law. She also said Rep. Gary Peters, D-Mich., who is running for Senate, “jeopardized my health” by voting for it.

Within hours of the AFP ad’s initial broadcast, media fact-checkers pored over alleged inconsistencies between her comments in the ad and statements she’d made in interviews, then said her numbers didn’t add up. Liberal pundits suggested they knew what was good for her better than she did. Peters sent a letter to television stations running the ad threatening their licenses if the “questionable claims” in the ad were not proven.
