Perhaps I am reading the tea leaves wrong or my cynicism has overrun my compassion. Irrationality is, of course, not confined to one side. Seeking God's help in political matters is not irrational, however. On the subject of healing, prayer has been shown in a variety of studies to aid physical healing and improve the probabilistic outcomes of surgeries and other treatments. As unexplainable miracles are sought and occur in medicine, so are they also sought and occur in politics.
Politicians seem eager to tap into whatever they can tap into to aid their causes.
God, in actuality or in concept, is or symbolizes wisdom, power, and goodness. Being one of God's people and seeking God's favor means to share in God's wisdom, power, and goodness. Faith seems to be a key to the extent that one can share in the wisdom, power, and goodness of being among God's people. It seems illogical, inconsistent, perhaps even unGodlike.
