Marc Thiessen provides the most likely reason President Obama tossed his plan for Syria to Congress in Why Obama’s sudden deference to Congress? He begins with some of the things Obama has already done without Congressional approval, to wit:
delaying the Obamacare employer mandate;
continuing aid to Egypt in spite of law prohibiting it after a coup d’état;
dictating the way immigration laws are enforced;
impeding domestic energy production; and
military strikes in Libya.
Mr. Thiessen goes on:
Why the sudden deference to the legislative branch? Simple: The limited strikes he intends to carry out will likely fail, and he wants Congress on the hook, so that Republicans cannot criticize his Syria policy when it implodes. ...
If he lays out a coherent strategy to deal a real blow to Assad, isolate al Qaeda, and help the moderate, pro-Western opposition come to power, then Congress should back him.
But if his only plan is the weak-kneed response the administration has telegraphed so far, let him act on his own — and own the consequences.
Funny in a way. Obama is trying to tar Republicans with guilt by association -- association with him!
Meanwhile, Senator Rand Paul proposed a resolution containing Senator Obama's own words from 2007. See Rand Paul's Syria Amendment Declares POTUS In Violation of the Constitution if He Launches Attacks Without Congressional Permission.
Finally, someone who can out Alinsky the community organizer in chief.
