More soft or uncommitted delegates may align with Trump and he could actually attain the 1237 early if the state of Washington yields 40.
It could yield up to 44. I agree with your thoughts.
Use the additional references near the bottom of this post.
Also, note the graphics, how many Trump has, and the fact that he’ll get almost all those remaining.
He stands a very good chance of coming in with nearly 1500 delegates.
