What do you mean by "on the dock"? As to running room, not at all. It is difficult to say if you support or oppose something without even a definition.

My guess is Prop 22 would still pass today, although by less than the 61% it did in 2000.
Rudy will crush the opposition in a GOP primary in California, IMO.
