Obviously the national party disagrees with you, otherwise they would have committed serious money to Illinois and we wouldn't be in this mess.
To help Jack Ryan? I think they smelled his dirty laundry coming. He knew well in advance of the nomination what was in his divorce records, and he knew they would be made public. Early reports before the nomination about his records had to make the National GOP a little wary. He should have "come clean" from the start, and that would have eased a lot of minds.
