How did gorbachev's policy of democratization change how elections were held in 1987?

In the past, voters could only approve candidates who were picked the communist party. Now, they could choose from a list of candidates for each office. Gorbachev gave way toward full-scale electoral democracy by taking initiative in changing the way the elections were handled in the past. There were multicandidate elections all over the country and at the same time unlimited nomination of candidates.
