How can you tell if a political party is brain-dead? Easy. It spends an entire campaign denouncing the incumbent as a smarmy, good-for-nothing liar, rather than outlining its own agenda. The Republicans tried it against Bill Clinton in 1996, the Democrats tried it against George W. Bush in 2004, and now in Britain the Conservatives are trying it, with equal lack of success, against Tony Blair.

Such a tactic is beguiling because, to True Believers, the other side’s triumphs are never on the up and up; they must be the result of hoodwinking the hapless electorate. The problem with this approach was pointed out to me by a political strategist last week: “Voters think all politicians are liars. So telling them that someone is a particularly effective liar doesn’t work.”

It especially doesn’t work for the Tories because they’re accusing Prime Minister Blair of duplicity on an issue about which they actually agree with him. Conservative leader Michael Howard says he would have supported the invasion of Iraq even without weapons of mass destruction — the subject of Blair’s supposed dissembling. By nevertheless making the L-word the centerpiece of today’s election, Howard comes off as opportunistic and unprincipled.

Just as Kerry did, when he tried the same approach.
