Trump entered the debate in his weakest position yet in national polls. Recent national polls show Clinton's lead in the high single digits. And it doesn't look much better for Trump in several key battleground states. SAUL LOEB/AFP/Getty Images
According to MJ Lee, CNN national politics reporter, Clinton's major challenge entering the debate was not so different from the challenge she's confronted over the past few months: presenting the country with a positive vision for her presidency that is detached from her argument against Trump.
