for attending the prayer breakfast. However, the idea that a common religion among politicians is meaningless when it comes to political positions. The idea that simply because both sides claim to be Christians there will be cooperation is plainly ridiculous.
A common religion, like Christianity, does not even result in agreement on religious beliefs. The continuous splintering into denominations and sects among Christians is all the evidence needed to demonstrate that.
Trump and Coons both claim to be Presbyterians, but a glance at the history of the Presbyterian Church shows that even that denomination cannot agree. It has split many, many times, over minor disagreements of doctrine and rules.
Christianity is the dominant major religion in the United States of America. That said, there is almost nothing one can say about Christianity that applies to the entire Christian community. The only real connection is one individual, who was supposed to have lived a a couple thousand years ago. Everything else is open to question among Christians
There is no comity among Christians regarding their own beliefs, so expecting there to be comity on political issues, due to a common religion, is simply foolishness.
