No, Trump believes only in himself and his racist and fascist fantasies. He has a record of dubious dealings and has even admitted in his speeches quite openly to doing everything from sending jobs to China himself, to bribing most the politicians to do things we don't like, to admitting to corrupting polls by fabrication (that one in his announcement speech even), to wanting to change the definition of citizenship, to wanting to push Christians and the Hispanics into the desert to die, to creating his own little "Deportation force", to wanting to plunder Iraq for the next few decades. I'm sure there'll be more madness from him too.
Cruz, Cruz has tried to defy Obama, but he has actually got very little done. Thing with Cruz that I would think is obvious to the Trump faithful is that Cruz can't be president, he's not a natural born citizen.
You want someone that gets stuff done? Me too, that's why I say get someone with experience and a proven record of prosperity. Like I have said Kasich, Jeb, and Huckabee, those are the only three with a record of getting prosperity done, of fixing government messes, and the proven record of beating Democrats in swing states, or in Huckabee's case beating the Clinton Machine.
