Trump down 2 since the debate as is Cruz. Trump at 38 last week. He’s actually been in the 36-39 range in this poll consistently since September. He may have bled off small support due to the last week’s scrum with Cruz, but it’s negligible. Trump has leveled off nationally, Cruz is on a slow but noticeable downswing. See charts at link.

Someone suggested that Trump’s really high 45 was the result of the Paris attacks. Sounds right.
