753px-ivy_mike_-_mushroom_cloudJudging by statements from leading senators, World War III will arrive around April Fool’s Day this year. That’s when Majority Leader Harry Reid pledged to install fellow Democrat Al Franken in Minnesota’s vacant Senate seat. But if Democrats try any such thing before former Sen. Norm Coleman has exhausted legal challenges to Franken’s recount victory in federal courts, Sen. John Cornyn threatens “World War III,” according to Politico.

UPDATE after the jump: It was a week ago that Cornyn said an appeal “could take years.”

Cornyn, who is chairman of the National Republican Senatorial Committee, has so far been winning a war of words with Reid over the standoff. Reid backed down from earlier vows to seat Franken after Republicans threatened to filibuster.

The rhetorical art of metaphorical war — a topic on which U.S. Rep. Michele Bachmann recently gave the nation a clinic — is likely to ramp up this week as anticipation grows for the impending decision by Minnesota’s three-judge panel in the election-contest lawsuit brought by Coleman.

UPDATE: Cornyn’s contention that a Coleman appeal in federal courts could take years is ricocheting around the blogosphere this morning, apparently because it’s again referenced in Manu Raju’s Politico post today. But Cornyn made that statement a week ago, after the Republicans’ weekly lunch last Tuesday, as Raju then reported. The full quote:

I know it seems it’s gone on for a long time already, but this could go on for a long time. Appeals take months, if not years, sometimes.

When and to whom did Cornyn make the “World War III” comment Raju reported for apparently the first time today? I’ve asked Raju that question by e-mail and will update again here if I get a response.
