The Class Reunion is considered the most political bar in Washington and to White House staffers it's the neighborhood saloon.

Jody Powell stops by frequently. Pat Caddell was a familiar face before the heat of the campaign. Ford administration members still hang around. Four of five Pulitzer Prizewinners can be there on a given night.

Politically, the bar is divided -- staunch Republicans holding down one end, dyed-in-the-wool Democrats at the other end, the two groups separated by lobbyists holding down the middle, with reporters hovering about the free telephone at the waitress station.

The trend on Election Night began to shift around 8 o'clock when the lobbyists moved their drinks closer to the Republican end of the bar. By 10 o'clock they were buying the drinks.

A Ford administration member, Hugh Cannon, showed up for his cold beer with a wide grin that had been subdued for almost four years.

"They'll be back at their same seats no matter who wins," said Joan Grbach, the owner, who left early for a party.

"It's a good indication the country has come to its senses," said public relations consultant Susan Dower when Reagan's victory became apparent.

By midnight, jubilation at the Republican end became quieter when word got out about the death of Leonard "Army" Armstrong.

Armstrong, a retired Marine captain and a strong Republican, had his spot at the end of the bar where he came each working day for the past eight years, sipped his salty dog or martini, passed on a few funny tales, talked politics and dreamed of a Reagan-run White House.

Early Tuesday morning, after casting his vote in Springfield, Va., Armstrong suffered a heart attack. He died at the Fairfax Hospital before knowing the outcome of the election.
