Anyway, back on point.
Trump isn't winning the GOP nomination, Cruz is. Cruz can get the others supporters as they drop, Trump for the most part, can't! Cruz will be seen as the compromise candidate between factions of those on the far right, and those in the middle of the party. He is also considered an outsider, wants to stop illegal immigration, so can become more than acceptable to Trump voters.
I thought for a very long time that Rubio was going to be the one to give Trump and Cruz the most difficult time. Well, he may be the most difficult, but it really won't be hard at all because he was on the gang of 8 and supported amnesty. HALLLLLLLLOOOOOOOOO, no Trump or Cruz supporter will touch him with a 10 ft pole. By my way of thinking, Trump, Cruz, and Carson combined have over 50% of the GOP support locked up. If/when Carson drops, if he gives his support to Cruz, the GOP nomination is then over.
The only hope the GOP has for slipping in a party moderate is a brokered convention, and I don't think that is going to happen. I believe Cruz will pick a party moderate as Reagan did to silence the establishment for VP, which means while I have absolutely no use for the man, that person would probably be Kasich.
Not to get to far into the weeds, but if that happens, it means Ohio goes GOP along with Florida, and the dominoes will already be falling before the election-)
