Before his death last week, conservative commentator Andrew Breitbart wrote a column criticizing President Barack Obama as a radical, which was published posthumously on his newly relaunched website.

The column, titled The Vetting, Part I: Barack's Love Song to Alinsky, focuses on Mr. Obama's work as a community organizer in Chicago and his participation in discussion panel for a play in 1998, while he was still an Illinois State Senator.

In 'The Audacity of Hope,' Barack Obama claims that he worried after 9/11 that his name, so similar to that of Osama bin Laden, might harm his political career, wrote Breitbart. But Obama was not always so worried about misspellings and radical resemblances. He may even have cultivated them as he cast himself as Chicago's radical champion.

The play, The Love Song of Saul Alinksky, follows the life of Chicago community organizer Saul Alinksky, who Breitbart also described as a radical.

It's radical leftist stuff, and it revels in its radical leftism, Breitbart wrote of the play.

Breitbart draws connections between Mr. Obama's past as a community organizer with Alinsky's, attempting to paint the President as a radical leftist and condemning the mainstream media for ignoring it.

Because the mainstream media did not explore his roots, the American public remains largely ignorant of the degree to which Obama's work with ACORN and his love of Alinsky were symbolic of his true political will, wrote Breitbart.

Breitbart goes on to extrapolate on the past activities of the other members on the panel in an attempt to link them with the radical left.

Are we expected to believe that 'Baraka Obama' was a countervailing voice of reason on a panel of radicals? asked Breitbart, making reference to an apparent misspelling of Obama's first name advertised with the discussion panel on a flyer for the play.

Breitbart suggested that Mr. Obama's participation in this panel reveals his radical roots, though it is the participation itself rather than the content of anything he might have said. Without any apparent documentation of that discussion, Breitbart seemed more than content to make inferences based on the participants.

Breitbart made it his duty to scrutinize the President's past in a manner he felt was being avoided by the mainstream media, a view that reflected his own conservative ideology that those who didn't share it couldn't be trusted to report the truth.

It will be up to Breitbart's former colleagues to carry his torch, a responsibility they seem more than willing to accept.

From today through Election Day, Nov. 6, 2012, we will vet this president--and his rivals, read a statement on, prefacing his last column. We begin with a column Andrew wrote last week in preparation for today's Big relaunch--a story that should swing the first hammer against the glass wall the mainstream media has built around Barack Obama.
