The filing deadline is tomorrow. I'd bet money that some dim (I'm thinking Loretta Sanchez) is thinking, "Hmm. I'm a woman, and a Hispanic, and throw in variables and unknowns for the other candidates, plus the fact I'm not in State govt and can't be blamed for the mess, and I might walk away with this thing if I can get, say, 23% of the vote..."
If Dim party "unity" didn't hold together for Davis, I can't imagine they're all going to fall in line for Bustamonte. I look for one more semi-prominant dim to enter the race at the last minute.
