Religions have been around since the begging of time, they may not have been labelled as "religions" but since the time of Prophet Adam (AS) people have been worshiping God. Back then there were no politics, there was just right and wrong. During the time of "kingdoms" they all followed religions and the rulers ruled by the religions. In our present time we state everything is a democracy and so on and so forth. But how are laws determined? How were they created? Based on beliefs of people, and the beliefs of people came from non other than religion. So like it or not they go hand in hand.
"Can religion and politics go hand-in-hand?" Of course! They often do. Not even just in [insert derogatory remark here] countries, but in the USA. Just look at marriage even mattering to the government. Our last president stated he isn't worried about the environment, because we don't know when Jesus will return.
Clearly politics and religion do go hand-in-hand quite often, even if they should not.
As evidenced by the theocracies in the Middle East in modern times and European countries using Christianity as a moral compass in past times, it's evident that using religion as a basis for/in addition to politics is a very unwise decision. Politics change the like the wind; religion does not. You cannot use the laws or morality of a religious text because the ideals and morals of one society will be vastly different than those following it.
Politics itself is corrupt it would just end up corrupting religion and compromising the liberty of the people. Which I believe, now don't take my word on it, but I believe that's what happened to the Roman Empire, they tried to mix Religion and politics Also the bible says give to Caesar (an emperor of the time) what belongs to Caesar and god what belongs to god
I am a religious person, but the 1st amendment makes it clear that the Government can't make religious laws, whether it be pro-religion (just in case you want to legislate religion upon the people) or anti-religion (whether you want religion to go away).
The separation of Church and State is a principle that should be respected.
