Beyond that, though, Jeb Bush and George Bush teaming up — great and kind men that they are — is just another reminder to a Republican base already in revolt that they need to keep up the revolt. Taking shots at Donald Trump by the Bush family is more likely to cause base level conservatives to rally around Trump than move on.

I know the Bush family must show its donor network they still have what it takes. They need to reassure people who have given millions. But I think the roadshow of the Bush Brothers emboldens their opponents more than their supporters and emboldens one opponent more than most — Donald Trump.

In trying to hurt Trump, they’re just going to help him. About the only way for the Bush family to hurt Donald Trump at this point is for Jeb Bush to withdraw from the race. That’s just a fact.
