Yes that is the way to pray. Ask God to intervene for the sake of the country and what is best for it, not that He reward one candidate and deny another, which is what praying for Coleman over Mondale, is doing. You are asking God to reward Coleman and punish Mondale. This surely is not God's way. But, if you pray that the country elect the best man for the job, for the sake of the country, He may just touch some hearts at the polling booths.
