No, he's just not drank the alt-right, anti-immigrant Kool-Aid. Back in the day, we used to call such folks conservatives . . . .
Back in 1954 Eisenhower deported about 1.1 million back to Mexico
Back in 196 Reagan set in motion Amnesty, which has functioned as a permanent magnet, bringing in unknown millions.
Bush II sought to repeat Reagan's mistake (essentialy a renewal).
Between 1954 and present, there have been just three Presidents/major cndidates that were strong versus illegal immigration; Perot, Buchanan and Trump.
