If you want to understand the fanaticism of the Chilean right, check out this op-ed in Forbes by someone from the Fundación Para el Progreso. It seems that "Misses Bachelet" (yes, he wrote that) is a communist tool set to destroy the Chilean miracle. It's quite a creative portrayal of Chile, so fundamentally blinkered and simplistic that all you can do is hope the weather is nice in his bubble.
And, of course, if you don't really have an argument then mention Hugo Chávez:
The spirit of Ms. Bachelet, whose government program basically aims to revive many of the failed policies implemented by Chile from the 1940s to the early 1970s, has led some members of the center right to accuse her of following the populist path of former Venezuelan President Hugo Chavez.
The person is writing as if Bachelet was an unknown, rather than an establishment figure and former president with a long track record of being decidedly un-radical. But with Bachelet poised to win the presidential election on November 17, maybe even in the first round, all the right has to offer now is fear.
