Democrats still see Joe Biden entering race

After the first Democratic debate, there has been much talk over wither Biden will decide to run for president or not. Many people find it hard to believe that Biden could even find a path after such a dominating performance by Clinton. However, the Jefferson-Jackson dinner is coming up, which happens to be the same dinner that in November of 2007, then Senator Obama, tore apart her chances of becoming president without even naming her. Could we see Joe Biden do the same in an effort to make his way into the presidential Race?
