President Bush dropped into St. Mary’s county in Maryland yesterday to give a Labor Day speech. But the state's two top Republicans -- Gov. Robert Ehrlich and Lt. Gov. Michael Steele -- were both very conspicuous no-shows. The response from the state Democratic Party: "This Labor Day, Ehrlich and Steele are afraid to be seen with the most anti-working-class president since Herbert Hoover, even while they gleefully count his checks for their campaign."
