That's how I prayed about it, but I also included Obama's need for salvation and a change in his heart and mind.
It's good to be open to God about everything.
Lord, I think these people in power are evil and corrupt and I ask that you stop them and, Lord, they need salvation and Jesus in their hearts and minds. Lord, it really bothers me what these people are doing, please help. In Jesus name, amen.
That's generally how the conversation starts.
