Corrupt congress and casual sonia?

Every time I hear abt corrupt politicians they all r associated with Congress party.If this had been few times one can say that to b a coincidence but everytime a gr8 Congress leader is always involved in corruption.....right from changing CM's of Maharashtra,Black money in Swiss banks,CWG scam,2g scam,hike in petrol/diesel leading to corresponding hike in basic commodities(milk,sugar,grain,etc)it is so common that we can expect a hike in next month-blame it to leaders like sharad pawar.I hv pledged this time I'm not going to vote to Congress....I am also sure that Congress is not going to make it this time.
