Rand is moving to the left as a political strategy to marginalize the Democrats and their hold on the Hispanic vote.
Rand is taking a cure from George Will, who suggested that the Republicans show a "willingness" to go to the left of the Democrats. . .

Make a stand for an unpopular policy move, and then balance the values for a long-term win.
