President Obama has scheduled a speech on national security tomorrow to counter Dick Cheney's address on the same topic at the American Enterprise Institute. Who will win? Obama's speech is meant as an olive branch to his fellow Democrats, who dealt him his first major setback by pulling funding for the closing of Gitmo after Republicans successfully argued that U.S. prisons are not prepared to accommodate suspected terrorists. Cheney's speech, meanwhile, will likely be yet another addition to the former V.P.'s intense campaign to convince Americans that they are less safe under the Obama administration.
