Actually WP consolidated it's position in this elections, and paved the way for a two party political scene. This is despite the PS and RK saga.
WP is also part of the reason, and I don't mean this in a bad way, for the poor showing of other parties, even PSP.
WP basically hogged the headlines, and voters basically compared their opposition candidates against the WP ones.
I think the political scene will change after this GE and like in past GEs, more good candidates will come forward and stand for WP.
