On the other hand, from Reuters:

Venezuela’s
opposition Monday rejected as a fraud results showing
President Hugo Chavez had won a referendum on his rule, and
said they would contest the outcome.
“We firmly and categorically reject the result … we’re
going to collect the evidence to prove to Venezuela and the
world the gigantic fraud which has been committed against the
will of the people,” opposition leader Henry Ramos Allup told a
news conference.
He spoke shortly after Venezuela’s top electoral officer,
National Electoral Council President Francisco Carrasquero,
announced to the nation preliminary official results showing
that Chavez had survived the recall vote.
Carrasquero said in a national broadcast the “No” option
opposing Chavez’s recall had obtained just over 58 percent of
the vote, while the “Yes” vote obtained nearly 42 percent.
“Our numbers … are very different,” Ramos said, adding
the opposition would ask international organizations who
observed the referendum to check the voting machines and
ballots.
