Vice President Joseph Biden will present the Top Ten list on "Late Show with David Letterman" tonight.
This will be Biden's second appearance on the show. He last appeared on Sept. 20, 2007, when he was running for president.
President Obama appeared on "Late Show" last month, but Mitt Romney has avoided late-night TV for the fall campaign. Romney delivered Letterman's Top Ten list in December, when he revealed the "top ten things Mitt Romney would like to say to the American people."
Update: The Romney campaign has issued "the top ten ways Joe Biden makes the case for a Romney presidency."
