Like I said in my previous response which you seem to have glossed over. His answer has very little to do with Cubans and everything to do with praising dictators.
You just don't do that if you want Hispanic votes to go your way. He just had to renounce and there would be no issue, he didn't, so it'll be used against him all over spanish radio and television if they feel they have to.
He clearly framed his response around the question and topic of the video.
In that frame he was discussing the failure of the Bay of Pigs invasion and some of the reasons why it failed.
The media as dishonest as is framed it as "praise for a dictator"....when the simple fact is that if you ask any scholar that values honesty, s/he will probably give you the same answer Bernie was voicing.
Daniel Ortega has been elected numerous times democratically so I am not sure how Daniel is now a dictator except for Reagan saying he's cause of the socialist tendencies of the Sandinista movement and Reagan's little Contra war....(of which Reagan should of been tried for war crimes - but again that does not happen to U.S presidents). (Univision trying to bunch him up as a dictator with Castro - goes to show what the representation of latinos is all about - latinos have no choice in the U.S but to watch their crap - theirs and Telemundo's (it's an oligopoly) - when it comes to agenda they're far away from being the standard bearers of "latinos").
Those videos and those records have always been there with Bernie. They were always going to be exploited by Republicans and his opponents no matter what.... the idea that now, in this specific moment, it's somehow a "surprise"......please...the media narrative perhaps.
I didn't gloss about the fact that majority of "latinos" (not Cuban) don't give a damn bleep about the Cuban lobby and their little war with Castro.
Fact is Castro is unanimously popular in Latin America (although diminishing from its peak years as generations come and go) and that thinking, although unpopular in the U.S doesn't disappear when they came over... it's only suppressed by expectations. Not to say all Latinos have favorable opinions of Castro, you have to realize that a massive amount of latinos that migrate to the U.S are mostly affluent enough to do so and usually represent the right-wing (or right wing thinking) in those countries so he does have high unfavorability with a certain block.
