In that case, Trump might not have to wait for NJ.
WA State next week could put him over the top.
My math has Trump at about 1160 including the PA unbounds and 19-20 delegates from Oregon. WA has 44 delegates. 30 are WTA 3 per the CD as long as Trump exceeds 50% in each CD (which he should). If it goes <50% in any CD, it's 1st place 2, 2nd place 1. The remaining 14 delegates are proportional statewide with a 15% threshold. It's possible (but not probable) Kasich or Cruz meets the 20% and takes a few delegates away from Trump. WA should put Trump at about 1205. He'll likely get to 1237 with a win in WTA NJ on June 7. (51 delegates, the first polls to close that day).
