I'm not certain it matters who wins the subsequent debates though I predict Romney will do so.
The American people have had enough of President Obama and are generally ready to dump him, they've just been waiting for someone to convince them that there's a real, safe alternative. It's been that way probably since the first budget debacle back in the summer of last year, certainly since last spring.
Romney's problem has been that he hasn't made the sale that HE is the that alternative. In Wednesday night's debate he made that sale. He proved to 67 million viewers that he was smart, compassionate, enthusiastic, competent, and more than able to step in and be successful.
I believe at that point, Romney won the election. Short of some really astounding occurrence, Obama is TOAST.
New gun law will help stop gun violence just as effectively as drug laws have helped stop drug use.
