They seem to forget that BUSH went to the Congress directly and got their blessing. Obama did not.
Obama is in violation of the War Powers Act...and it's that simple. he's trying to weasel his way out of it with lawyers.
You are correct that Bush asked Congress for permission, but the administration also clearly stated they did not require congressional approval.
Bush says he doesn't believe the WPA is constitutional, but follows it.
Obama says it clearly is, and ignores it.
Which of those positions is more reprehensible?
That's a false dilemma.
