Joe Biden tops a list of Democrats who may be interested in a 2016 presidential bid, but appears to have stepped a bit ahead of himself Saturday.
Video posted online by the site Mediaite shows the vice president stumbling over his title at an inauguration party in Washington.
"You saw what America came to see. You saw early on, Iowa Democrats saw early on the incredible promise and the incredible capability, the incredible leadership of the guy I now serve with," Biden told supporters at the party, sponsored by the State Society of Iowa.
