George Simion, leader of the right-wing Alliance for the Unity of Romanians, summed up the intent of the demonstrations his party organized:

"We are protesting against the coup d'état that took place on Dec. 6. We are sorry to discover so late that we were living in a lie and that we were led by people who claimed to be democrats, but are not at all. We demand a return to democracy through the resumption of elections, starting with the second round." 

In November, Romania held the first balloting in its two-round election. It resulted in Europe's latest instance in which a populist, nationalist, right-wing candidate posted a result that far exceeded what polls indicated he was capable of. In a 13-contender field, that candidate, Calin Georgescu, led the pack with 23%, setting him up to advance to the second and final round against reformist Elena Lasconi of the Save Romania Union party.

However, just two days before that second round was to take place on Dec. 8, Romania's constitutional court annulled the election, and ordered a complete do-over of both rounds. Their justification: Supposed Russian meddling manifested in manipulated votes, campaign irregularities and secret spending. The ruling came after incumbent President Klaus Iohannis reportedly shared intelligence claiming Russia organized thousands of social media accounts to boost Georgescu's campaign.

"You petty politicians, with your ungrateful and immature games, you won't even know what hit you in this global storm," said Georgescue in a social media post in which he promoted the protest and compared Romanian leaders and judges with former French president Nicolas Sarkozy, who's on trial on corruption charges. "You are so small that you aren't even able to understand anything. Nothing you do will make a difference anymore. The inevitable, is inevitable." 

On Sunday, crowds -- estimated in size from tens of thousands to more than 100,000 -- marched through the streets of Bucharest, with Reuters reporting that many left-wingers joined the protest. The slogans on their signs included "We Want Free Elections," "Bring Back The Second Round," "Freedom," and "Democracy Is Not Optional." In a country that is among the most religiously observant in Europe, many carried Christian Orthodox icons.
