Amid complaints of racial profiling of Hispanic people, the Obama administration has pulled the plug. As if the Arizona border is being overrun with illegal immigrants from somewhere other than Mexico.
Why would the White House put a stop to the arrest and deportation of illegal immigrants? Because they've got their eyes on them as voters after the desired amnesty becomes reality. And the Democrats are not shy about placing electoral politics and special interest concerns over the defense of America.
The borders must be secured. If the federal government can't (or won't) do the job, more power to law enforcement agency willing and able to do it.
