Julian E. Zelizer, a professor of history and public affairs at Princeton University, lays down the case Obama can make for a second term as president:
President Obama must make the difficult transition from being the candidate who once ran as the maverick - the agent of change - to the candidate who now represents the political establishment. There is no way to escape this.
Rather than seeking to change the status quo, to some extent he must defend it to voters. The new message that he must craft for them is important, not just for re-election, but because it could help shape how he's perceived in the next four years, should he win.
