LYING ABOUT LYING IS NEVER A GOOD IDEA…. I didn’t occur to me that Christine O’Donnell blatantly lying about her educational background would turn into a multi-day story, but it just keeps getting more interesting.

The story started when O’Donnell claimed to have graduated with a bachelor’s from Fairleigh Dickinson years before she actually earned a degree. It got worse when we learned that O’Donnell lied about having studied at Oxford, and lied again about post-grad work at Princeton. It got even worse when O’Donnell lied about a fellowship at Claremont Graduate University.

By way of a defense, O’Donnell’s poor campaign staff argued yesterday that the bogus claims were part of the candidate’s LinkedIn bio, but O’Donnell wasn’t responsible for that unauthorized bio and she shouldn’t be blamed for its inaccuracies. That, of course, didn’t make sense — there have been media questions about information from that LinkedIn page for weeks, and neither O’Donnell nor her team ever questioned its veracity. Indeed, when reporters asked yesterday why the campaign never challenged the authenticity of the bio before, the staff couldn’t answer.

Just when it seemed the story couldn’t get worse for the extremist candidate, it gets worse.

[T]he claim that Christine O’Donnell studied at Oxford has now turned up on a second O’Donnell online resume, this one from ZoomInfo. […]

This morning, the Democratic National Committee pointed out that O’Donnell is also described in a ZoomInfo entry as having achieved a “certificate” in “Post Modernism in the New Millennium” from the “University of Oxford.” The Zoom Info entry was labeled, “user verified.”

ZoomInfo, which has spent the day looking into this, has sent over a statement detailing what happened with this profile. According to the company, O’Donnell’s profile was claimed in 2008 through something called a “double opt-in process.”

The only way that resume, with its patently false claims, could have been published is by O’Donnell posting it to the site. She had plenty of opportunities to correct it, but chose to leave the falsehoods in place.

Worse, TPM found instances in which O’Donnell told similar lies on her MySpace page, 2008 campaign website, and 2006 campaign website. She included deceptive information about her education in court filings, and repeated related false claims during recent media interviews.

This wasn’t a typo or sloppy word choice.

In other words, Christine O’Donnell lied, and then lied about lying. This, coupled with her suspected campaign embezzlement, suspected tax fraud, background in witchcraft, rejection of modern science, hatred of gays, anti-masturbation efforts, and hysterically extreme political worldview, makes her a U.S. Senate candidate who’s literally hard to believe.

Update: Wait, one more piece of evidence has emerged. Those working for the O’Donnell campaign probably aren’t well grounded anyway, but this story is unspinnable.
