Islam is indeed a religion.
If the person elected accepts that the US Constitution is the supreme law of the land, they serve. Very few Christians will say that the US Constitution stands above the Holy Bible. But they serve.
Besides, in order for the person to be there, they had to have won the majority of votes (or electoral votes). For you to try and say the person can't serve is ridiculous.
Islam is not a religion (see Post # 75) thus the "religious test" has no relevance.
Problem is Muslims DO NOT accept that the US Constitution is the supreme law of the land, they serve. They believe the Koran (and its Sharia law) is the law of all land, and they have no nation other than the Ummah.
Muslims have no nations. They have only the Ummah (worldwide community of Muslims) that receives first loyalty, above all else, including nations, and their Constitutions.
As such, for example, a Muslim in the USA, would have more loyalty, kinship, allegiance to another Muslim in France, Russia, Somalia, Pakistan, or Australia (or anywhere) than to a fellow American, living here in the USA.
Or a Muslim in Poland would have more allegiance to a fellow Muslim in Brazil, than any fellow Pole. A Muslim in Denmark would have more allegiance to a fellow Muslim in China, than a fellow Dane, living right next door. They have only one nation >> the Ummah (worldwide community of Muslims)
It's obvious that you are not well versed on this subject (nor are most people in this thread) and are easily duped by the likes of Keith Ellison, Andre Carson, Ilhan Omar and other Muslims deceitfully (by taqiyya) weaseling their way into the US government, to carry out the now 28 year old Muslim Brotherhood plan (the Explanatory Memorandum) to destroy America FROM WITHIN >>
The process of settlement [of Islam in the United States] is a "Civilization-Jihadist" process with all that the word means. The Ikhwan [Muslim Brotherhood in North America] must understand that all their work in America is a kind of grand jihad in eliminating and destroying the Western civilization from within and "sabotaging" their miserable house by their hands, and the hands of the believers so that it is eliminated, and Allah's religion is made victorious over all religions."
