The tough talk is often laced with humor. Following a disastrous first debate in Denver, he ridiculed Romney's plan to cut the deficit, saying his opponent would only commit to ending the federal subsidy to PBS, the equivalent of getting tough on Sesame Street characters Big Bird and Elmo. "Oscar is hiding out in his trashcan," Obama joked later.
During a rally in northern Virginia, Obama said his rival had caught "Romnesia," causing him to forget past positions on issues.
Jokes aside, Obama regularly casts his presidency as the result of a movement, a coming together of a diverse group of voters who wanted change. The message is full of self-empowerment, with the president telling voters a second term rests upon their shoulders.
"We've come too far to grow fainthearted," Obama says. "Now is the time to keep pushing."
In a few days, he will know the outcome.
