GOOD FOR SEN. JEFF FLAKE (AZ)

He's one of the saner Republicans in the Senate and I'm glad he openly doesn't support Trump:

DICKERSON: What’s your understanding of how he’s going to handle the estimated 11 million undocumented immigrants in America?

FLAKE: You know, that’s not clear at all.
(Byron York also noted an inconsistency in Trump's Phoenix speech):

First, Trump's statement that those here illegally would have "one route and only one route" to legal status seems clear. Everybody seeking legalization would have to leave and then return.

But then, a few short paragraphs later, Trump said that "in several years," when tough enforcement measures are fully in place — not contemplated, not in the planning stage, but actually up and running — then "we will be in a position to consider the appropriate disposition of those who remain."

FLAKE: Well, it becomes increasingly difficult to see that he’s going to change.
So, I don’t expect that I will be able to support him in November. I would like to, but he’s the Republican nominee. I just don’t see how I can.

UPDATE: Trump responded by insulting Flake, calling him weak and ineffective.
