YOUR SATURDAY MORNING. Cancel your plans. Set your alarm. Make tonight an early night. I'll be on C-SPAN starting at 7:45 a.m. Eastern time tomorrow to chat about politics, the weather, whatever. It'll go until 8:30 a.m., and I have a hard time imagining you have better things to do at the crack of dawn than roll out of bed and enjoy my sonorous soliloquies.
