Seems like tulsi' numbers are regression to the mean and landing where her peers are.  The over all dissatisfaction with the legislative branch came more from the GOP/tea party approach of eating tax payers time and money on opposing everything and anything obama did (often not successfully).  Tulsi is not a part of that mess. 
I personally like that tulsi is a vocal and principled leader.  But I admit she is different from the other Hawaii legislators but I think that is a positive with hawaii having a variety and diversity of personalities and styles.  It serves Hawaii well that we can have different approaches in getting things done and representing our state.
