For the second time in less than 24 hours, ABC identified Michael Reagan as a “conservative,” but failed to identify the left-wing ideology of Ron Reagan Jr. ABC played up the “clash” between the adopted son Michael and Ron, author of a new book that claims his father, the 40th president, had Alzheimer's during his time in the White House. Shipman explained, “It's another feud in an often fractious family. In a series of tweets over the weekend, Michael Reagan, the former President's son and a conservative commentator, accused his stepbrother Ron of trying to sell out his father to sell books.” As the MRC's Brent Baker pointed out, Ron Reagan Jr. previously hosted a show on the left-wing MSNBC and now appears on the network to provide liberal commentary. Shipman played clips from a 20/20 appearance last Friday in which Reagan Jr. promoted his book and asserted that he simply had an “inkling” that his father had Alzheimer's in the White House. Ron Reagan is not a medical doctor and Shipman didn't point out that there's evidence for this claim. Instead, she parroted, “Ron also writes 'I've seen no evidence that my father, or anyone else, was aware of his medical condition while he was in office. Had the diagnosis been made in, say, 1987, would he have stepped down? I believe he would have.'” The liberal author will appear on Tuesday's GMA to promote his book. Will his ideology be mentioned by host George Stephanopoulos? A transcript of the January 17 segment, which aired at 7:11am EST, follows:
