Is it just me, or is Obama just plain odd?

I voted for him, but won't again in 2012. Sure, he has a ton of charisma, but I think the novelty of the first president of color has worn off. From not putting his hand on his heart during the Pledge Of Allegiance (no, it's not required, but the others were doing it), To bowing to Arab leaders and refusing to wear a flag lapel pin. I'm not saying he should conform, but there are certain behaviors the POTUS should follow and respect. He does sometimes seem contemptuous of America and Americans.
