With his air of reasonableness and moderation, he has projected a remarkably likable persona. Even in the midst of a historically dirty campaign for re-election, his likability numbers remain impressive, as seen in a recent AP-GFK Poll that found 53 percent of adults have a favorable view of him.

But beyond the spin and the polls, a starkly different picture emerges. It is a portrait of a man quite unlike his image, not a visionary reformer but rather a classic Chicago machine pol who thrives on rewarding himself and his friends with the spoils of public office, and who uses his position to punish his enemies.

Peter Schweizer captures this other Obama with a bracing statistic in his book “Throw Them All Out,” published last year. In the Obama economic stimulus program’s Department of Energy loans, companies owned and run by Obama contributors and friends, like Solyndra’s George Kaiser, received $16.4 billion. Those not linked to the president got only $4.1 billion. The Energy Department is far from the only federal program in which favoritism has heavily influenced federal grants.
