My quick impressions.
President Obama was hesitant, thinking on his feet instead of rattling off rehearsed lines. He didn't do a good job of defending his signature domestic achievements: guiding the economy through the worse recession since the Great Depression, financial reform to insure against a repeat, and health care reform to extend coverage to tens of millions of Americans and improve coverage for all. Obama missed many opportunities to point out that Romney's promises sound good, but there is nothing behind his "plans."
After the jump, my impressions of Romney and my overall winner.
