This is actually pretty clever politically although come November not too many people are going to remember it.

Barack Obama will kick off his general election campaign Tuesday in Minneapolis-St. Paul at the Xcel Energy Center - the site of the GOP convention:

Senior political officials tell Politico's Mike Allen that Sen. Barack Obama (D-Ill.).is likely to hold a huge rally Tuesday night in the Xcel Energy Center in St. Paul, the site of the Republican National Convention from Sept. 1 to 4.

Tuesday is the night of the final Democratic primaries, and the choice of venue is a mischievous, aggressive way for Obama to unofficially kick off the general election campaign against Sen. John McCain (R-Ariz.). The location gives huge meaning to the moment, with Obama likely to frame a tough case against his new opponent in the very hall where McCain will accept his party's nomination.
