I don’t think people are warming to Trump so much as his message. Also, they are relieved to finally see someone in power (economic power in Trump’s case) with the guts to point out publically that the Emperor has no clothes.
He also fights unapologetically. GOPe types would buckle the first time some media grunt challenges them or calls them a name. You an see their brains burning as they have to think about the right answer. With Trump (and Cruz to some extent) he knows what they believe and doesn’t have to find the weasel words to back away from a media challenge. That’s the difference between being authentic and being a phony.
You nailed it. It is Trump’s message and his unapologetic exposure of the rape of our country by illegals that has caught fire with the grass roots.
On the economy he speaks from a position of accomplishment and strength, while giving hope of changing our economic environment for the better.
Do I think he can accomplish any of these things better than Cruz? No, but he has put them front and center where they need to be in this election.
