Last week I mucked about with this RCP delegate predictor tool. Even when I was ebign generous to Trump, I still couldn't get him to 1237. IIRC I think 1183 was the best result I could generate for him. It's why I felt there was definite mileage in laying him given that he was heavy odds on

The hypothesis still stands, and after his lacklustre rallying call last night which sounded both tired and even more aimless than usual, I think Trump is starting to realise it. I'm beginning to wonder how he ever closed a deal in his life!
Basically Ted Cruz has a black belt across the plains states, possibly extending into Arizona even. Kasich was always likely to emerge as a threat in in Indiana, Wisconsin, Pennsylvania, and possibly Maryland, Delaware and Rhode Island
I don't see how Trump can make any inroads into the Cruz black belt. The result from Missouri has probably shown it actually with St Louis in the east going Trump, and Kansas City in the west going Cruz. The boundary line runs down the state. Trump has to go west of the Rockie to win again, and that means Oregon, Washington and California. I suspect Kasich will have some traction in the Pacific states. Oregon is proportional which would probably be the least Trump friendly of the three
I can certainly see the Cruz vote migrating to Kasich in the east and north, but am less sure that the Kasich vote will migrate to Cruz. Then again, Cruz might not need it to win the states he needs to win. He'd likely win Montana, Wyoming, Utah, Nebraska, the Dakotas and Colorado without them (CO is unallocated anyway so Trump won't pick up any skin there). It leaves New Mexico and Arizona as Trumps only possibilities from this black belt, albeit NM is proportional too
As the race starts to tighten and the possibility of Cruz winning a contested convention dawns on folk it seems logical that he will come under greater scrutiny. Cruz is a dominionist, a really scary guy who thinks he's a king sent by God to keep America on the righteous path etc. I really can't see this playing out well in California and Washington, and forget it in New York, Conneticuit and New Jersey
At this stage I'm inclined to think Trump will come up just short but will be the moral winner. Can the GOP really deny their membership their choice? It depends how close to 1237 he is I suppose
Trump appears now to have a ceiling of about 45% in the south and 40% in the north. He also has a hard floor of about 35% and 32% too
The west coast and mid west seemingly hold the key, with Arizona also being critical as a bit of a stand alone
If the #nottrump alliance of Rubio, and Kasich with some Cruz can stop Trump in the mid west (and there's grounds to think they can) it will be contested. Would be worth crawling through the combined Rubio/ Kasich vote for Michigan, and Illinois, and see what it tells us about Wisconsin, Pennsylvania and Indiana. Mind you, we'll need to see this registration irregularity resolved in PA
