(ANSA-AFP) - BUCHAREST, MAY 2 - With 1.3 million followers, a Donald Trump-supporting far-right candidate is riding a wave of popularity on TikTok ahead of the rerun of Romania's presidential election in which he is expected to win Sunday's first round. Authorities are keen to avoid a repeat of the uproar that followed the constitutional court's annulment of last year's vote results, after claims of Russian interference. Authorities also reported a mass social media campaign in favour of far-right candidate Calin Georgescu, who won the first round. Georgescu was barred from the rerun and now his ally George Simion, leader of the far-right AUR party, has taken the lead, according to several opinion polls. "We're going to show them that we can beat them," the holder of one active TikTok account under the name of adi.suveran, promoting Simion, told AFP. "If Simion doesn't win, it's clear the elections have been rigged." The Chinese-owned video-sharing app has nine million user accounts in Romania, which has a population of 19 million. (ANSA-AFP).
