One week after it was first reported that he would suspend his campaign, and one day after he gave supporters “insider, advance notice” of his plans via a Web video, former House speaker Newt Gingrich (R-Ga.) on Wednesday afternoon will bring to a conclusion the long, er, conclusion of his White House bid at an event in Northern Virginia.

Our colleague Chris Cillizza at The Fix takes an in-depth look today at Gingrich’s campaign and his potential legacy after more than three decades in politics.

While it remains to be seen what’s in store for Gingrich after Wednesday, a big part of his legacy — at least as far as the current campaign is concerned — is this: a litany of attacks against the presumptive GOP nominee, former Massachusetts governor Mitt Romney.

The Obama campaign seized on that trove of Gingrich attacks in a Web video Wednesday – a reminder that while Gingrich himself may be stepping away from the spotlight over the next few months, Democrats are intent on keeping the former House speaker’s remarks very much alive.
