"I am afraid she'll listen to voices in her head, thinking they are divine inspiration, when confronted with national security issues. What if God tells her to launch the missiles?"
(Usenet post about Sarah Palin, then running for vice president)
The argument sounds right but I do not think it is.
When you get in an airplane, do you worry about whether the pilot is a fundamentalist? What if God tells him to fly into a mountain? The mechanic who checked it? What if God told him not to bother — everything was fine? If you go in for an operation, is whether the surgeon believes in evolution one of your main concerns? What if God tells him to cut out your heart and put it on an altar? When driving down the highway do you worry that perhaps one car in ten coming the other direction is driven by a religious believer who might decide that this is his moment to go to heaven?
There is evidence all around us that people can hold apparently weird religious beliefs and still do a competent job of dealing with the real world. Perhaps that means that they do not really believe in the weird beliefs, that they are a story they enjoy telling themselves but not part of their picture of the world. Perhaps it merely means that knowing how to fly an airplane or use a scalpel does not depend on your view of religion, so pilots and surgeons who happen to have odd religious beliefs nonetheless learn and practice their professional skills the same way other pilots and surgeons do.
Whatever the explanation, I think it is clear by ordinary observation that holding weird religious, or for that matter political, beliefs rarely makes one unable to live one's life with an ordinary degree of competence.
Getting back to the specific case of Palin …
Sarah Palin: A Digression
In 2008, when Sarah Palin was running for vice president, a variety of sources, including the AP and Reason Magazine, published versions of the following:
"Alaska Gov. Sarah Palin told ministry students at her former church that the United States sent troops to fight in the Iraq war on a "task that is from God.""
It was, to be blunt, a lie. The full sentence, which can be checked from the original video on the Huffington Post, was:
"Pray for our military men and women who are striving to do what is right. Also, for this country, that our leaders, our national leaders, are sending them[U.S. soldiers] out on a task that is from God, that is what we have to be praying for"
By snipping the rest of the sentence, the AP and lots of other sources converted "I hope this is true," which is what "pray that it be true" implies, into "this is true." It is a striking example of how a partial quote can be used to attribute to someone something she did not say. What she actually said implied that she did not know if it was God's plan or not, which suggests that she does not have voices in her head to answer such questions but must make up her own mind.
Just like the rest of us.
Religion, Irreligion and Rationality
Religions serve at least two purposes, both important to humans. One is to help make sense of physical reality, explain, for instance, why living things appear to be brilliantly engineered creations. The other is to make sense of life, to answer questions about what we ought to be doing and why.
The development of science over the past few centuries provided a strong rival to religion for the first purpose, an explanation that not only covered the same territory but came with much stronger evidence for its truth. One might hear stories about occasional miracles at Lourdes or elsewhere but one directly observed the miracles of science every time an electric light was turned on or an illness cured.
Science did not provide an alternative for the second function. People responded in one of two ways. One was to retain their belief in the religion and reject any parts of modern science that they found inconsistent with it — in its more extreme form, the fundamentalist option. The other was to give up serious belief in the religion and adopt some substitute: Environmentalism, Liberal politics, Marxism, Objectivism, New Age superstitions.
Two things started me thinking about this situation. One was a conversation with a college freshman very upset to discover that the church she was now attending blended environmentalism, which she does not believe in, with Christianity, which she does believe in. The other was a piece in the Wall Street Journal offering evidence from polling data that religious people are, religion aside, less given to what most of us would regard as irrational beliefs, than non-religious people.
The effect is not small.
The Gallup Organization, under contract to Baylor's Institute for Studies of Religion, asked American adults a series of questions to gauge credulity. Do dreams foretell the future? Did ancient advanced civilizations such as Atlantis exist? Can places be haunted? Is it possible to communicate with the dead? Will creatures like Bigfoot and the Loch Ness Monster someday be discovered by science?
The answers were added up to create an index of belief in occult and the paranormal. While 31% of people who never worship expressed strong belief in these things, only 8% of people who attend a house of worship more than once a week did. (Article in the Wall Street Journal)
Which gets us back to the question of whether the fact that people are religious is a reason to expect them to behave in irrational ways, hence a reason not to want a religious person as President. Judging by the evidence in the article it may be the other way round. It is the non-religious President we should be worried about because of what he might believe instead; he might convert a projected three foot rise in sea level into a thirty foot rise out of pure faith in an avenging Gaea and adopt policies accordingly.
Fortunately, Al Gore lost.

Everybody worries that *other people's* religions make them crazy. Including followers of the fashionable secular religions of the left.
<offering evidence from polling data that religious people are, religion aside, less given to what most of us would regard as irrational beliefs, than non-religious people.>
This is a non-sequitur as many religious people don't believe in the things you're positing the non-religious ("spiritual" and "lefties") believe in at a greater degree as part of their religion.
In other words, if you ask a religious Christian fundie about speaking with the dead, they'll either say, "no, that's against the rules," i.e. the parable of Lazarus and the rich man, OR they'd start spouting their belief in NDEs, which, if you've ever heard any fundie Christians talk about, is just as nutso as a cheap New Orleans psychic talking to your dead grandmother on your behalf.
The reason many (maybe most) Christian right-wingers don't "believe in" climate change isn't because they're more rational, it's because they either oppose the left on principle, or believe "God is in control," or a combination of those two things.
IF you polled the religious right about God healing cancer, bringing people unexpected money, finding them a lower mortgage rate (Sam Harris), healing their cataracts (Tim Minchin), talking to them about life decisions, yadda, yadda, yadda, the polling would probably level right out.
What's more crazy: Thinking God healed grandma's arthritis after you prayed in tongues or believing in Bigfoot?
I mean, personally, I think Bigfoot is more credible. And Atlantis and Mu being based on real places.
I don't believe those things, but I'd believe them before believing in healing prayer causing aunt Jane's breast cancer to be less severe last summer (even though, Praise Jesus, He took her home in the fall).
Here's the real issue to me:
Right-wing fundie Christians of a certain stripe (and I'm speaking from experience, having been one myself) believe without a doubt that in order for Jesus to return, the Temple must be rebuilt and perfect red heifers need their throat slit.
In order for this to happen, bye-bye Dome of the Rock...
So, yeah, Al Gore's craziness is not missed - but imagine a POTUS who's trying to decide in a very gray situation about whether to go from Defcon 3 to Defcon 2 or even more scary, Defcon 1, and he or she is thinking (maybe even a bit subconsciously) that the ONLY way Jesus is going to come back is if the Dome of the Rock is not there anymore...
There's also a class of Christians, I heard one who was badly injured say this after returning from Iraq, "I couldn't kill anyone that God didn't already ordain to be dead at that time."
