I think that ticket would be favored against Hillary. As terrible as Jeb is, Hillary is very overrated.
She leads Jeb by 20 points.
Opinion polls at this stage, especially nationwide ones, are meaningless.
I disagree. Even though Obama is unpopular with many people, Hillary still crushes every GOP opponent by >15 points. What does that tell you? Hillary is much stronger than Obama ever was because she can appeal to white voters in a way that Obama can't.
Is there verifiable evidence that Obama was particularly weak among white voters outside of the South? If so, one marvels at how he won Iowa, New Hampshire, and Wisconsin by much bigger margins than Gore/Kerry.
