The Governor of California should be impeached if within the first sixty days of taking office he hasn't called a special meeting of the western state's governors to address the issue of illegal immigration. The Governors of California, Arizona, New Mexico and Texas should join together to put the federal government on notice. Either it takes care of the border issue, or they would.
They could resort to using the national guard or they could call up their state troopers to enforce the sovereignty of their own borders. They are sworn to do so. Either they are fulfilling their sworn duty or not. If not, adios.
