Answer
Boris Yeltsin was Ryzhkov's main rival in the 1991 presidential election. Yeltsin was a reformist who wanted to move Russia away from communism and towards a more democratic and capitalist system. Ryzhkov, on the other hand, was a more conservative candidate who wanted to maintain the Soviet Union and its socialist system. Yeltsin won the election by a wide margin, and he became the first president of the Russian Federation.
