On further consideration this would be an extremely crafty move by the Republicans. Just imagine the Democratic base reaction to it. Heads exploding all over the place. “But…but…they’ve got a black guy AND a woman! But they’re Republicans! And Chewbacca lives on Endor! AAAAGH!” <splut>

To clarify a bit more, a reason for a bump might be something like a particularly good debate performance, a positive interview, a successful ad campaign, an endorsement from someone influential, a direct competitor dropping out of the race or saying something to turn voters against them, something like that.

Well I would think that his winning the Florida Straw Poll happened because he was doing a lot of campaigning down in Florida. (Not that I’ve been following his campaign too closely, but usually straw poll wins are accompanied by heavy campaigning in that state.) Then when he wins one straw poll, the news media pays more attention to him, people learn about him and consider him more electable than they had previously, and pledge their allegiance to him in the other news polls cited.
