Passage: The referendum would go ahead, but since the impeachment vote failed, the Congress of People's Deputies sought to set new terms for a popular referendum. The legislature's version of the referendum asked whether citizens had confidence in Yeltsin, approved of his reforms, and supported early presidential and legislative elections. The parliament voted that in order to win, the president would need to obtain 50 percent of the whole electorate, rather than 50 percent of those actually voting, to avoid an early presidential election.

Question: How many percent of the whole electorate does the president have to obtain in order to win?
50 percent
