Somebody posted a link on another thread a few days ago that showed Biden's DNC speech from 2008 playing alongside the one from last week. They were not identical, but the bullet points were the same, and some of the phrases were the same. So, his "home-run in the bottom of the 9th" speech was basically warmed over from 2008. And Biden was a lot more forceful and alert in the 2008 version.
Since he gave the same speech as 2008, I guess that means he and Barack didn't get the job done in their 12 years.
