Biden also has shown a willingness to give his boss credit, even when his advice has been rejected, mostly notably after he urged Obama not to go ahead with the U.S. military raid that killed Osama bin Laden. When the raid succeeded, he praised the president's resolve and decisiveness.
The relationship between Obama and Biden has worked, say those who know them, because Obama is comfortable hearing the vice president's counsel, but also because of Biden's embrace of his role as adviser rather than top decision-maker.
"They've been through a lot together and there's a lot of mutual respect there," Kaufman said. "The secret is Obama's stood by the deal and Biden's stood by the deal."
