Chavez warned that McCain represented the same mentality that characterised the "terrorist" Bush administration.
 
The Venezuelan leader said he had better communication with the administration of Bill Clinton, the former US president.
 
"Independently of who wins the elections, we are hopeful and it is within our plans to enter an era of better relations with the US government," he said.
 
"At the least one would hope for the level of relations we had with ex-President Clinton."
