Actually Jack, Chavez was no fan of our President:
Chavez's anti-American rhetoric, which reached a peak during the administration of former president George W. Bush, continued during the Obama administration.
After Obama voiced concern that Chavez's government had aided Colombia's FARC guerrillas, Chavez said Obama had "the same stench" as former president Bush.
For his part, Obama has said that now that Chavez is dead, perhaps relations between out two countries can improve.

Chavez was a tyrant in many ways, and now he's gone. Not to worry, we will never run out of tyrants.
