A May 18 WorldNetDaily article by Aaron Klein quotes Israeli politician Effie Eitam as favoring an Israeli attack on Iranian weapons facilities. Klein describes Eitam as "chairman of the National Union Party," but he never identifies the party's political orientation. That's because it's a right-wing party, one that presumably falls in line with Klein's political orientation as demonstrated by the bias shown in his WND articles.
While Klein regularly identifies the political orientation of Israeli parties and politicans if they are left of center -- for instance, a December 2005 article by Klein describes Israel's Labor party as "leftist" and another politician as an "extreme leftist" -- but Klein rarely points out the orientation of right-of-center parties and politicians.
UPDATE: Here's some background on Klein's labeling bias.
