There are two things that lead me to look at this a little differently--the way that Ted Cruz is "apparently" courting the Donald Trump voter, and something Jeb Bush just said today. When people indicate that they believe that Ted Cruz is hoping to pick up Trump's core audience when the celebrity reality-show star eventually flakes, I think they are missing a few details--for one thing, Ted Cruz hails from a border state. He is comfortable speaking the language of border security; people might think it's a pose or look at it as weird for Cruz to take an anti-immigrant or perceived anti-Latino position when his father is a Latino and an immigrant. But they are wrong in trying to box in Cruz's identity (take this "villager" attempt at identity politics minstrelsy). The point is, you would be hard-pressed to get to the right of Cruz on any issue and his natural style is bombast. Thus, he "gets" Trump. You can't look at Cruz and think "minority outreach" because Cruz is a dues-paying conservative and minority outreach isn't his problem.
