Barack's Lincoln Strategy

Isn't Barack Obama carrying this Lincoln thing too far? Being sworn in on Lincoln's bible is OK and eating the same meal as Lincoln after the ceremony is fine also. But not since Lincoln has Northern Virginia been cut off from the capital. Local news here claims the closing of the bridges across the Potomac were meant to stop a possible Mumbai event. What? Were terrorists in zodiacs aiming to sail up the Potomac? Perhaps the cut-off should have been just south of Richmond where Sarah Palin claimed real America began.
