Impeach.
When Bush repeats the mantra, “...take the pressure off the border”, it can only mean the removal of that demarcation line. It also has within it the attempted demise of US sovereignty.
Bush swore to “faithfully execute the laws” of the United States; he did not take an oath to see they’re revised to fit his new world order. He has failed and deliberately sought to undermine the laws he swore to see executed.
For that, I’m nearer the point of supporting the call for his impeachment than I’d ever been.
