There was much to be bothered by in yesterday's display on the White House lawn and siding with a foreign government was too much to ignore.
In his criticism of the Arizona/US law, Obama effectively set the bar for any future immigration legislation. He was very careful to word his statement that the current law has the potential for abuse. Therefore, the standard by which he must measure any subsequent law is set. And it is an impossible standard.
Effectively, under the Obama declaration the border is open.
That is Obama’s sole skill-—re-framing the “narrative.”
