when she committed to become hart's chair, the house job was not open since takai had earlier stated that he would be running for reelection.  so you cannot say that she is reneging on her appointment to hart; one must be do what he/she feels that they can do the best for all. if she decides to run for congress, she can do it with a clear conscience as she will be helping the whole state not just Honolulu's rail system.
