Democrats bumped their gaffe-prone Vice President, Joe Biden, from primetime on Thursday night to ensure he does not say anything that bigfoots President Barack Obama's address to the Democratic National Convention.

In Biden's stead, Sen. Dick Durbin (D-IL), the bland senator who will do no harm, will introduce Obama before one of the most important addresses of Obama's career. 

Biden, who is often undisciplined and frequently goes off his prepared script, caused a stir when he told a Virginia audience, half of which was black, that Republicans were "gonna put y'all back in chains." And this move shows Democrats do not completely trust Biden to stick to his script, especially if he knows he has a national audience before him as he eyes a potential 2016 presidential run. 

Biden's son, Beau, and wife, Jill, will introduce Biden before Biden formally accepts his party's vice presidential nomination. 

CBS and ABC will air the DNC during the 10 p.m. hour while NBC will air the 9 p.m. and 10 p.m. hours because the networked aired the New York Giants versus the Dallas Cowboys on Wednesday night.
