Devdatto After the Haldia election you must have understood what "Scientific rigging" is.Few of the EVM showed much lesser votes in total but when the total votes received by the candidates were added up then it showed a much high figure.How is this possible?((This was covered by a lot of channels and newspapers).Without tampering the machine software this is not possible.Mamata was intelligent enough to understand what "Scientific rigging" was even before these reporters did understand.Its a pity that you still down't understand.
