Well put, and on reflection, you're right that some here have convinced themselves that she's virtually unstoppable.
My own view is that while she is certainly beatable, we underestimate her at our peril. She is cagey and ruthless. I saw her on one of the Sunday talk shows during the Dem primary season and was deeply struck by how much more ably she handled herself than any of the Dems contending for the nomination.
That's not saying much when you consider Al Sharpton and Dennis Kucinnich were the competition. I don't think we will elect someone as evil as she is.
