Mike Huckabee has a weird spike in this poll.  However, the biggest problem for Jeb Bush is the continued erosion within the Republicans being polled.  The “splitter” group (Fiorina, Huckabee, Christie, Rubio, Kasich, Perry, Graham, Pataki, Gilmore) cannot pull enough specific state-by-state primary support to create a pathway for Jeb if Bush remains under 15-20%.
Thanks entirely to Donald Trump, the GOPe road map is further collapsing this week.
