From my piece over on the home page:
For more than a decade, there has been tension in American politics about what to do about security at the Mexican border. Some see illegal immigration from Latin America as a problem to be solved by paths to citizenship or open borders. Others consider a strong, strategic wall the answer. Yet despite popular support for the latter, the former continue to muscle forward. In states like Arizona – where violence by illegal immigrants has led the legislature to pass and the governor to sign a tough new law mandating aliens to carry immigration documents – the border remains porous, devoid of funding for concrete and cameras, with Washington standing idly by.
It wasn’t always this way.
