How does a candidate with a net worth of 1 billion pesos under oath in his SALN spend 1 billion pesos in campaign spending?!

Mind you villar himself admits that he received very little or negligible donations... so where does he get the money?

Besides even if you say he has other sources of money then why weren't they declared in his SALN? Nobody is one billion pesos liquid and is still very rich after spending the same.. think about it...something is terribly wrong in this equation...
