And there's still eight more days until the 2011 extraordinary session (for redistricting) convenes. 26 white Democrats in the LA House left, about half of whom are in marginal seats and/or are in a position to get screwed pretty badly by redistricting. I would not be surprised at all to see a few more party switchers in the next week.
You'd think this would be a catastrophic event (i.e. a bunch right after each other) rather than staggered like this. Either the LA Republican party is promising them sweet deals sequentially or each of these reps are waking up from 4-month comas in turn
Most likely, it is a little bit of both.
