Besides the fact that Jeb just isn’t very likable I don’t think people want a Mexican dwarf for First Lady. Especially after the horrid one we’ve had for 7 years
I think Jeb's wife is a deal-breaker in much the same way that Theresa Heinz-Kerry was.
That woman was a disaster in the making, and didn't fit the public's image of an American First Lady in any way. Remember how fast they got her off the campaign trail when she started talking?
