Why does Pres.Obama do this?

His cabinet now has an individual that has commited Income Tax evasion.Tim Geithner..The fox guards the henhouse.And its a sad day that Republicans in the Senate voted for him,I am now convinced we have ALL been duped by our 2 party system though they appear to be so against each other and so FOR the people...Look what has happened to our country. Does anyone else see this?
