I've added some opinion links.
Mark Steyn is one of the best (and funniest) of the younger commentators. Steyn's weekly column is at the Chicago Sun-Times.
WFB is just the best. Buckley's columns are at National Review.
William Rusher was NR's publisher for 31 years. He's brilliant and fights with class, like a gentleman. Rusher's columns are found at WorldNetDaily.
