Joe Biden introduced President Obama with a powerful testimonial to the President's accomplishments and his character.
Speaking from the "ringside seat" he has occupied during Obama's four years in office, Biden focused on a personal perspective of the President, calling him by his first name throughout the speech.
"Barack Obama is our President because he always has the courage to make tough decisions," the Vice President said to a cheering crowd.
After the speech, MSNBC's Chris Matthews observed that Biden's "loyalty to the President couldn't have been more on display tonight."
While the majority of the speech focused on Obama's accomplishments, especially the bailout of the automotive industry, Biden didn't hold back from lashing out at Romney in his characteristically conversational way.
"Folks, the Bain way may bring you firm the highest profit," he said, referring to Romney's tenure as the head of private equity firm Bain Capital. "But it's not the way to lead your country from its highest office."
He also joked that Romney's much self-touted jobs tour would "have to be a foreign trip" because of "all his support for outsourcing."
