It's a mixed bag. Since the 90s there have been many relatively successful leftist-ish movements (MAS, PSUV, and to a lesser extent PT and PJ) through elections, but any of their victories is almost inevitably met with extreme reactions from bourgies, which shock the economy, but the news corporations owned by those same bourgies then peddle that the issue is some nebulous "corruption problem."

On the other hand it's really hard to build revolutionary movements because we have had severe counter-revolutionary dictatorships in our countries being propped up within living memory, on the mere suspicion of revolution. It's an ebb and flow, but those right wingers usually have USA backing and are not purely internal or homogenous developments.

True, but the media everyone consumes tells people that that’s bad, plus true leftist movements get instantly fucked over on the international stage.

Plus leftism is still wildly unpopular in Latin America, despite a few major successes.
