as for how and why people ignore and toy with the war powers act?
There is a belief that the war powers act is unconstitutional, usually held by whichever party is in power, and no one wants to test that in the supreme court. Both parties want the power when they hold the exec branch, but hate their opponents having it.
so once again...
Its all Kabuki theater by all sides with an exceptionally hostile GOP being driven by the radical right social angendistas and the Teabaggers.
If this could have won in court it would have by now. Let them test Obama now, and the hawks will turn to doves in front of an angry electorate.
Its good politics for Obama. He is playing the GOP on this one.
Boehner is outclassed in his job. He has been useless since he got in there, passing resolution after resolution that never sees the light of day in the senate and just withers away.
Wake me up when he writes legislation that makes Jobs, as he promised, or Writes a bill that the senate will consider and the president will sign.
Until then, the man is a useless drunk, desperate to regain the attention of the media.
