I'm not going to get into the anti-christ thing because my study has lead me to an understanding of Revelation that is opposed to that of Calvinism and/or the premillenialists viewpoint.
However, praying for leaders is the right thing to do. For instance with the current prez, your prayer would be directed in this manner.....
"Heavenly Father, I pray that our leaders will seek Your guidance and look to You in all that they do. Your will be done in all things."
Does that mean our leaders will seek the guidance of God? Not necessarily. But, your petition to God was that they would. That's all you can do. Remember, God allowed the Assyrians, Babylonians, Medes, Greeks, and Romans to come into power in order to fulfill His purposes. Jesus reminded Pilate that Rome wouldn't even be in power were it not for His Father in heaven. We seldom, if ever, can see the full picture when the events are happening, but God knows what he's going to accomplish and what needs to take place, we don't need to worry about that.
