Obama likes to have people smear Hillary nonstop here 24/7 but whine when she tosses any criticism at him. Maybe he's spoiled because he comes from a wealthy family. He whines that he is a nice guy, but Hillary is a monster.
Throwing the kitchen sink is an expression that refers to using everything you've got to win a race against an opponent. People in any kind of race have to be courageous, and give it your all. Obama wants it all and he wants it now -- his way. He's naive, and egotistical, maybe that's change that some people want but it does not seem fair to me.
Really if Obama can't take the heat he should get out of the kitchen. He thought that he is a "star" and becoming President would be a a slam dunk for him. Obama likes to parade around as if he's different. He's been attacking Hillary, all along, at first she was easy on him, and respecting him because he is another Democrat. He liked that, but when she finally starting using "the Kitchen sink against him" she won, and he's running scared and whining about it.
The problem is Mccain will throw a truck at him and flatten him like a pancake. You need to be thick skinned to be in politics not underhanded and thin skinned like Obama. That's why people say he is inexperienced, he has a huge ego and not patience for hard work or climbing the ladder to the Presidency. He wants it now, but does not want to face the challenge as others do. So he says he's "different". Yeah, that is different. Not a winning attitude, but different.
