Less than a week after Washington Post ombudsman Deborah Howell said the newspaper had an "Obama tilt," we were reminded again today of the paper's institutional bias against conservatives. Two columnists, Howard Kurtz and Joe Davidson, are guilty.

Kurtz analyzes whether Sarah Palin has gone overboard in her attempt to dispel leaks from bitter McCain campaign staffers. He counters Palin's criticism of "the rumors, the speculation, even in mainstream media, that Trig wasn't actually my child." Kurtz says that's not true:

In fact, no mainstream outlet published the Internet rumors until the McCain campaign issued a statement, during the GOP convention, that Palin's teenage daughter Bristol was pregnant.

The Washington Post printed Robert Novak's column about his brain tumor today, but it substantially edited the ending. The Post removed a mean-spirited quote from Joe Wilson and Valerie Plame attacking Novak that appeared in the version distributed by Creators Syndicate.

The original column by Novak ended like this (emphasis added, more below the fold):

There are mad bloggers who profess to take delight in my distress, but there's no need to pay them attention in the face of such an outpouring of good will for me. I had thought 51 years of rough-and-tumble journalism in Washington made me more enemies than friends, but my recent experience suggests the opposite may be the case.

But Joe and Valerie Wilson, attempting to breathe life into the Valerie Plame "scandal," issued this statement: "We have long argued that responsible adults should take Novak's typewriter away. The time has arrived for them to also take away the keys to his Corvette."
