It's always better to pray for the right decisions to be made by anyone or any government. You can always ask God to help these people and guide them to make the right decisions anyways. Putting your faith in God in these issues is always the sensible thing to do.
The scripture says to pray for those in leadership positions over us. The bad decisions they make shows a heart problem, not so much a mind problem. I pray that God's hand would be on them, that He would influence and guide them. And that He would touch their hearts and help them to see their need for Him.
