Heard it on CNN and it seems to have disheartened the Bush camp so much they've pulled him off the campaign trail at least for today. Fox News is speculating as to why he is holed up in the White House when he should be out stumping.
Various theories as to why people are not coming, but there is talk about dropping the "loyalty oath" to get people to come.
Any other info about this development would be welcome. My personal theory is that Jeb told him he can't steal Florida for him again without risking prison.
