For anyone saying "Eh, this won't be that big of a deal" you have no idea how much Castro is hated among Cuban voters in Miami. There are, literally, no words for the level of hatred, anger and disgust at Castro. Bernie refusing to walkback his praise from Castro was a guarantee he would lose the state.
A GOP nominee needs Cuban voters. Trump was already losing them by a point or two. If this is confirmed, this will be everywhere in Miami-Dade tomorrow, and he will be so royally fucked i'ts not even funny.
Also, I'm Priorities, I'm cutting an ad once I read this. I'm putting pictures of hardworking Americans with the voice saying "He didn't pay them for their hard work" and then cut to Fidel "But he had no problems paying him." And then I'm running that 24/7 all day, everyday in Florida.
