Nebraska Gov. Pete Ricketts started off his first term as governor this week by having to condemn a Republican member the state board of education, Pat McPherson, for running a conservative political blog that repeatedly referred to President Obama as a “half-breed.”

Ricketts stopped short of calling for McPherson to resign, as the board of education member pled ignorance and vowed to take down the blog. McPherson claimed that he did not write, or even read, the controversial posts on his blog, but refused to name the author. As the Omaha World-Herald reports, it is difficult to decipher who authored each post, especially since McPherson started attempting to scrub the website:

In all cases, the postings were unsigned. McPherson said Tuesday that “on occasion” he may have posted anonymously to the site, but he said the controversial posts were not his. “They weren’t speaking for me,” he said. He said he usually signed his posts. A computer word search of the website turned up no articles indicating they were authored by McPherson, though the search may be incomplete because many of the prior postings had been deleted by McPherson along with the offending ones.

McPherson’s blog, as it turns out, has a lengthy record of posting offensive material.

In October, the blog posted a cartoon portraying Michelle Obama as obese and featured as its “thought of the day” a tweeting saying, “Barack Obama is what happens when Affirmative Action and The Peter Principle have a baby.” It also shared a birther joke: “Did you hear about the guy who managed to get into the White House without credentials? And then just the other day some guy jumped the fence.”

Other entries, as reported by the Aksarbent blog, criticized the “homosexualization” of the Boy Scouts and lambasted the government for “creating special classes for gays, lesbians, transgenders, cross-dressers, aka., queers and perverts.”

Another entry mocked the Lincoln public school system for trying “to make sure the littlest transgenders feel welcome at school,” adding: “The problem in our educational system is not a money problem. If anything our schools have access to entirely too much taxpayer money, if they can waste dollars on such foolishness..”

Another post likened gay marriage to bestiality: “I vote Democrat because I love the fact that I can now marry whatever I want. I’ve decided to marry my German Shepherd.”

Last year, McPherson’s outlet accused Warren Buffett, the Nebraska billionaire and philanthropist, of waging a “war on babies.”

In August, McPherson’s blog reposted a column by conservative writer Doug Patton saying that America is now worse than Nazi Germany thanks to gay rights and legal abortion:
