She has run what has to be one of the most incompetent Senate campaigns in recent memory. Nelson would have his way with her in a general; it's really embarrassing. The Bushies didn't want her to run because they saw how she kept losing margin in her Sarasota district while alienating potential supporters. The Sarasota seat was one of the safest in the country, and Katherine found a way to screw it up.
Really, the only way Nelson gets beat is if Jeb gets in the race.
Otherwise, this is a Dem Hold.
Be Seeing You,
