Bush's attempt to find a safe ground in the immigration debate appears to be failing. At this point, many on the left just don't trust him to do anything right, and those on the hard right appear to hate it. They are demanding mass deportations, and the fortress USA approach.
This issue is important, but this year it looks like it will just be a political football for the boys (and girls) in DC to play with. One day they might get serious and deal with what is driving the inflow of immigrants, until then we will waste billions of dollars, and do nothing to fix this.
