Aye, it is a very important issue.
Governance, and religious views ought to be seperate for the simple matter that many people simply do not believe in certain aspects, or all of religion.
Either way, it seems to me most governments ought to be in control of the people, and thus enact a true democracy, not a system in which you vote for a person to represent you.
It may well be that you agree with 60-70% of what the person you are voting for says, but regardless the remaining 30-40% or more is still a big gap in opinion.
These systems are falsely called Democracies, when in fact, by definition they are a Republic.
