MOSCOW, NOV. 27 -- Rivals Mikhail Gorbachev and Boris Yeltsin, whose confrontations comprise the continuing soap opera of Soviet politics, fought to a draw today in the Russian republic's full legislature.

From the balcony, Soviet President Gorbachev watched with nodding approval as Communist Party deputies tried to get the Russian parliament to bring up for a vote the Kremlin's new draft Treaty of the Union. Yeltsin, the Russian president, who has called the draft far too conservative, tried hard to shift the agenda to economic problems.

Yeltsin warned that with the entire country facing the "threat of famine" this winter, the session of the republic's full parliament had to concentrate on the "essential issue" of feeding the people.

{Milk is the latest food item to disappear from Moscow's stores. Deputy Mayor Sergei Stankevich said Monday that nine Russian regions have announced they are stopping deliveries to the capital, the Associated Press reported. Stankevich also blamed the crisis on "shopping sprees and hoarding."

{The capital's Communist youth newspaper, Moskovsky Komsomolets, reported that Moscow has received 100,000 fewer tons of milk so far this year, and that production of cheese and sour cream has had to be cut accordingly.}

For Gorbachev, the Treaty of the Union is the critical element in reordering both the political and economic relations between the republics and the center, Moscow.

Although Yeltsin is the master of the smaller Russian Supreme Soviet, he appeared taken aback by the pro-Gorbachev forces in the larger Congress of People's Deputies. Ivan Polozkov, leader of the conservative Russian Communist Party, spoke for Gorbachev when he told reporters that there "can be no economic reform without resolving the question of Russia and the union."

Had the Communist deputies succeeded in getting the Russian legislature to approve Gorbachev's draft, it would have been a stinging defeat for Yeltsin. But during a break in the session, Yeltsin met with members of Gorbachev's entourage and worked out a compromise: the legislature would limit itself to an "exchange of opinions" on the draft treaty rather than a vote.

The proposal passed by an overwhelming majority. Later, Yeltsin tried to take the edge off his often difficult personal and political relations with the Soviet leader, saying that continued confrontation between him and Gorbachev is "unacceptable."
