Barack Obama is an atheist, and he runs the United States. Would you just rule him out for that? Not so likely. Besides, most atheists tolerate Christian 'high US government officials" so it should be equal. Studies do not show a difference between Christians and atheists in such stances, so it is to be equal.
Classic Republican dogmas such as limited government, personal property, the right to bear arms, and free market capitalism can all be attractive to people of no religion/atheists/agnostics. The majority of Republicans may be religious, but that doesn't mean that religious affiliation is a prerequisite. Their political beliefs require no religious faith in order to be agreed with.
Republicans can be non-religious. Being religious doesn't make a person a Republic. Many devout Jews are Democrats, and many atheists are Republicans. Being a member of a political party doesn't guarantee you a corner on the religious market, and being religious doesn't guarantee what political party you will choose to be in.
It depends on what defines your affiliation more, economic beliefs or social issues. I say yes because of economic ideas. There is a significant population of people who believe in markets, capitalism, etc. But also believe in gay rights, evolution, and are pro choice. This causes a problem because liberals won't have them because of their economic views and conservatives won't have them because of their social and religious views. I consider this to be a Republican stance because I think that economics drives what goes on in the government in terms of debate. That isn't to say that social issues aren't important, they are, but look at what candidates talk about when they run. It's all the economy. Plus if there is a true separation of church and state, the views of many Christians should not be defined as political views, just religious views.
It's true that many religious people vote republican, especially in regards to social issues such as abortion and gay marriage. However, many republican's social views aren't tied with religion. For instance, you don't need to be religious at all to believe killing an innocent person is wrong, so if you believe a fetus is a person, then killing it would be murder. Euthanasia, at best. Gay marriage could be opposed on the grounds that it negatively affects the children that homosexual couples could have. Now, these don't reflect my views. In fact, I believe the opposite. However, it's important to realize where the views of republicans really come from rather than just dismissing it as religious dogma.
I'm sure many Republicans are non-religious and get into politics simply because they want to help people. Conservatives and Republicans aren't all necessarily Christians. Fundamentalist Christians are, as a general rule, Republicans, but the reverse is not true. It would be like saying all Christians vote for Republicans. That most certainly is not true either.
Of course. I have met many. We are after all a secular country with a specifically secular government; therefore political alignment does not necessarily have to come with religious affiliation. The fact that most republicans ARE religious only shows that the ideals they are after are shared by people who tend to be religious, too.
In 2016 Trump won many people over and who identifies himself as a non religious person. He won over people who didn't always agree with him. In spite of her dirty mouth his ideas were successfully sold to the American voters. In record numbers he won his race for president.
Of course. I'm a Buddhist and a staunch conservative as are my family and all of my Asian and Asian-American friends. Most Asians in America lean conservative especially ones brought up in real Buddhist teachings. While most Buddhists believe in doing no harm and avoid criticizing or haranguing those of alternative social convention, most would be against gay marriage, fluid gendering, the welfare state, abortion, etc.
Anyone can choose which political party they wish to follow. Sure, both sides may conflict with each other, but as long as that party does not conflict with a person's faith/beliefs, then I personally believe they may choose that side. I know many Christian democrats, and many non Christian republicans.
Right now, a strongly religious element is in control of the Republican party that would not tolerate someone who was not Christian or possibly Jewish. This means that a non-religious person (or follower of a "non-Republican" religion like Islam) might want to vote Republican, but this person will never actually be able to run for office as a Republican or otherwise get anywhere within the party.
I know several Republicans who identify as "atheist" or "agnostic" but while individuals may hold these beliefs, as a group they are not and, for the foreseeable future, will not. The simple reason is that religious organizations are to entrenched in the Republican party. This is the way it has been since Reagan. Maybe sometime in the future they will stop being overtly religious but that has yet to be seen and there is no indication of this happening.
