Reading about this makes me so sad. I wonder if the people who supported Chavez back then still support him now?

Well Chavez is dead, but there are still some people supporting Maduro and his regime, those people are completely indoctrinated with that ideology.

There is no way not to blame Chavez and his regime for this disaster, they had and still have total control over everything. If everything goes bad, they are the ones responsible. But fanatics will always exists.

From what I understand, there's still no end in sight and Chavez's party is still in control, is that right?

That is right. 6 days ago there was a presidential election and Maduro won. Now it is up to the international community to fix this.
