Seems to me that you're advocating comprehensive immigration reform. No thanks. Let's build the fence first, without getting bogged down in interminable negotiations about other measures that may or may not hold up in the courts.
Then once the southern border is secure, we should consider the other measures one-by-one on their own merits and in terms of judicial and political realism.
Otherwise, it seems to me that your preference for comprehensive reform makes it more likely -- not less likely -- that illegal immigration across the southern border will continue unabated for the immediate future.
