Right-winger on a roll in Chile: José Antonio Kast, an ultra- conservative politician who pines for the days of Augusto Pinochet's dictatorship, has ridden a wave of anti-immigrant sentiment to the top of the polls ahead of next month's presidential election. He's currently at 21 percent, one point ahead of leftist former student leader Gabriel Boric. Talk about political whiplash: it was just a few months ago that Chileans elected a broadly leftwing constituent assembly to rewrite the country's Pinochet-era constitution in the wake of mass protests about inequality. But Kast, an avowed free-marketeer and social conservative, has tapped into rising resentment against the vast numbers of migrants – in particular from Venezuela and Haiti – who have arrived in the country in recent years. Last month, for example, saw an outbreak of violence against Venezuelan refugees in the northern city of Iquique. Kast has called for digging ditches along the borders and wants a special police force to root out illegal migrants. In the last presidential election, Kast got less than 8 percent of the vote. This time he's making a race of it.
