I tend to agree with POTUS having sole control to authorize urgent strikes but Iraq, Libya, and now Syria were all cases where congressional approval should have been sought and for Libya it wasn't so I think he's making the ethical move to ask congress, even if it is obviously a political clever one too. Also I like making congress take formal stances on military action since otherwise they can claim whatever position is currently political advantageous down the road.
They might, unless it just gets murdered a lot of republicans and Hawk-ish Dems will vote for it on general principle same as other won't. They don't always act strictly in accordance with whether they like or dislike POTUS.
Not all the Syrian rebels, or even likely most of them, are Al-Qaeda, anymore than those pissed at Mubarak were Muslim Brotherhood.
