This, to me, would be a negative, insofar as one of the main complaints is against the Bush dynasty. He changed to “Jeb!” To escape the Bush name, then hauls out Barbara, and W, and even his son, to campaign for him.
This shows just how desperate Jeb has become. He has no more arrows in his quiver.
Jeb ran as “Jeb!” in his first gubernatorial race in Florida in the 90’s, so that’s not new or to escape the Bush name. That was after 41 but before 43. But I agree W coming out to help looks a little desperate especially after Mom trudged through the snow to secure a fourth place finish in NH.
