Contested Democratic convention

See Abramson's article here on the topic. He starts by pointing out that his WI prediction was much closer than the polls or 538. Same for other primaries or caucuses. He based it on data that the others have either ignored or repudiated. (See the article for details.) He predicts that Sanders will win NY 51-49, PA 52-48, NJ 51-49, and CA 54-46. Sanders will also win in CT, RH, IN, WV, NM, MT, ND and SD, with Clinton winning MD, Virgin Islands and Guam. Since neither candidate will receive the needed pledged delegate count by the convention, he also predicts it will be a contested convention with both candidates vying for the superdelegates to decide.
