That was certainly was a subdued, almost kind-hearted Donald Trump. I don't have a sense of how that will or won't play. But I will say this. Trump's campaign from the start has been about immigration - booted out undocumented workers, slamming the door on Muslims. There was never much to hit Cruz on on the immigration front. There's a ton to hit Rubio with. He made his pitch to be the Republican who delivered his party for comprehensive immigration reform. And he failed miserably. Trump's script writes itself. Even more than usual.
