Gov. Parris N. Glendening called on the leaders of the state Democratic and Republican parties yesterday to refrain from political activity Wednesday -- the day after Maryland's primary election, and anniversary of last year's terrorist attacks -- and officials with both parties said they would comply.

"While our electoral traditions include a day of frenzied activity after a primary, this is a date that should remain uncluttered by politically charged rhetoric," Glendening said in a letter to Democratic Party Chairman Wayne L. Rogers and acting Republican Party Chairman Louis Pope. "This is a day for solemn reflection and remembrance."

David Paulson, a Democratic Party spokesman, said candidates would be encouraged to stop campaigning Wednesday.

Pope said: "I don't agree with Parris Glendening very often, but I have to agree with him in this case."
