You put too much emphasis on Indiana in that post. He could lose that with 0 delegates (he'll get some and perhaps win, but let's assume 0) and still be in fine shape. Assuming he wins California and NJ like he should, he would just need 50-70 delegates out of the 222 available in Nebraska, WV, Oregon, Washington, Montana, New Mexico, and South Dakota. Hardly asking a lot for the front runner.
