When Gray Davis pulled his little trick during the California Republican primary and helped to defeat Riordan, he did it by running ads against the presumptive front-runner that would sway the opinions of primary voters - Republicans. Jeb Bush, seemingly trying to pull the same trick, ran ads against the presumptive loser - McBride - which were designed to appeal to Republicans who for the most part wouldn't be voting in the primary.. What was he thinking? Apparently he's used his massive campaign chest to increase the name recognition of McBride.
If conventional wisdom is right, and Jeb is more worried about McBride than Reno, he may have completely blown it. Via Hesiod, who has similar thoughts.
