It's basically a George W Bush Redux. It advocates no useful policy on enforcing the borders. It merely advocates (buried way down on page 20) to reaffirm the right of states to enforce immigration laws - a right they already have.
And I'm gunna go out on a limb and wager that it says nothing about eliminating racial preferences or CRA.
But it's opening lines are the best. "America is more than a country. America is an idea...America is an inspiration to those [immigrants] who yearn to be free..."
Republicans have learned nothing from the Bush years. It's not a question of whether or not GOP policies will win votes, it's a question of whether they will actually make America better. We already know the answer to that.
