There have been many times that I've heard liberals say that. "If Jesus were walking among us today - that He'd be a Democrat." These folk seem to get it all ass-backwards. If Jesus were walking among us today - He'd be neither Democrat or Republican. Jesus would have nothing to do with man's corrupt politics. God isn't even WITH America. It's a nation that needs to be WITH GOD. Those who really want God to bless America need to keep in mind that we need to be pursuing His way - His righteousness - His forgiveness - His kingdom. God doesn't follow man. It is man who must follow God.
"Blessed is the nation whose God is the Lord" - Psalm 33:12
