Those who fail to learn the lessons of history

Apparently, I'm not the only one who noticed the eerie echoes of Watergate in the Rathergate affair.

Incidentally, the Republican Party acquitted itself far better than the Democrats during the Clinton impeachment or CBS in this scandal. They let Nixon know that he could not count on their support during an impeachment trial, forcing his resignation. Is obstruction of justice so much different from perjury?
