Bill Clinton, the former President of the United States will play a central role during the Democratic National Convention. His aides said he would formally place the name of President Obama into nomination during a speech to be held at prime time.

Clinton’s prominent role, which will be announced during the day on Monday, signals the Obama campaign’s effort to do everything possible to rally national Democrats when they meet for the national convention for their party in Charlotte, North Carolina.

Even more importantly is the national audience of voters who will view the former president’s address carried by all the major television networks. A top strategist for President Obama, David Axelrod said that there is not anyone who has better perspective over the past two decades than does President Bill Clinton.

Joseph Biden, the Vice President will appear at the convention the final night. He will make a case for Obama in front of the week’s largest audience in an outdoor speech. President Obama and the Vice President will also appear together prior to accepting the nomination from the party for another four years at the White House.

Recently it has been unusual for the vice president to not be given time on the stage alone during one night at the national convention. However, in his planned speech his aides said, Biden will remind Americans about the past four years along with all of the accomplishments the administration has made during what has been a very difficult economic time.

The Clinton invitation signifies just one more milestone in the evolving and complicated relationship between the ex-president and the current president.
