KMT legislator Lee Sen-zong (李顯榮) is no longer a KMT legislator. He is switching sides to the DPP, resigning from the KMT and making it clear he hopes to run for the DPP in Taipei County-01. He is considered one of those "Pro-Wang" legislators.
Most interesting is that the KMT central committee had offered Lee a spot last year as #12 on the at large list, a safe seat, but he declined before bolting. He is rumored to be doing this as a protest of sorts for the KMT primary procedure.
I imagine the DPP has already told Lee they will accommodate his switch, if for no other reason than to encourage a few other guys to jump ship. Expect at least a few more!
