One thing I want to address is this idea of Constitutionality. Obama's NOT overstepping his constitutional powers with regards to Libya. The constitution says only congress has the right to DECLARE war. The last time we declared war was WW2. Legally speaking Vietnam, Korea, Iraq, Afghanistan, Gulf War, etc. were all NOT declared wars by congress.
If you call Obama out for violating the constitution by conducting Libya-you have to call out Bush (both), Truman, etc. for doing the exact same thing.
BTW-I don't support what he's doing in Libya-I don't think it's any of our business. Just saying some people don't really understand what's in our constitution.
No, he is supposed to go through Congress to get authorization to use military force unless there is an imminent threat to the US.
