Havana - Cuban Vice President Carlos Lage said on the eve of elections in the United States that the world needs a US president who is rational and intelligent, rather than mad.
"That can't be too much to ask," said Lage, who is considered a supporter of economic liberalization on the communist-ruled island.
He spoke at the opening of a trade fair in Havana.
US President George W Bush, who leaves office in January after eight years, has been a harsh critic of the Cuban regime.
