I maintain that the overwhelming majority of the time when "God" is invoked in the political field, it is being used as a club to bash people into line and promote religious ideas.

It is appropriate, then, that politics is referred to as the skillful use of blunt instruments.

Your observations may be somewhat different from mine. I don't know where you reside but I know that in the US, for example, 'God' plays more part in politics than it does here in Australia.
