Su Tseng-chang will step in for the DPP candidate and Frank Hsieh will drop out. A possibility or not?
It seems there are forces work against Frank Hsieh already. Perhaps to be expected, and parhaps part or the plan. Let him take the brunt of the KMT offensive, and then closer to election time bring in Su Tseng-chang with little time to attack him and he gets to go into the elections as a clean candidate.
