I expect NZ to swing back to National strongly in 2020. I just find her so unappealing and rigid.
You gotta give Jacinda credit for being shrewd enough to win the support of NZ First. She must have offered something significant to make this happen, and English likely offered nothing to them, assuming they'd just fall in line because their politics were so closely aligned. YYYUUUGE mistake. She did what was required to take power. English played it safe and got burned. Give her the credit she deserves.
