The highest elected position in the Roman Republic was "C. Consul," since it was in fact two Consuls that ruled that entire Roman Republic for quite some time.
I don't know exactly what your looking for but, it could do with religion or different ideas of the country.
For example: Let's say that America goes to war with Russia and the Americans didn't want to go to war. The people have a differed idea from the government, meaning that the military does not have the peoples support.
Hope it helps!
