I was disappointed by this week's Democratic debate. Sanders wasn't in control, he lost his composure and wasn't really prepared to tackle questions about foreign affairs. On the other hand, Clinton was strategic and tactical without believing much of what she was saying.
Bernie is where he is because his message is super-simple (like Trump's) and because a large portion of the electorate hates Hillary. He's also too old in my view and I question many of his abilities to govern. Can he even delegate? I'm not so sure. Clinton's main mission is to get elected; if she gets there, she'll have time to figure how to get re-elected for a second term.
