I would certainly agree that there is a subset of the population that can tolerate less uncertainty in life. They percieve little control over the environment.
This can be seen in anxiety disorders where the individual engages in the cognitive distortion of catastrophising. The individual cannot predict the future and this leads to thinking the worst.
Cognitive theory would argue that these cognitive styles are put down at a young age as we learn the rules of the world.
If we don't feel secure as kids we can view the world as somewhere that we must make safe to reduce our risk of harm and consequent anxiety.
To stretch a point you could argue that your goofy president is trying (in his own head) to make his environment safe the only way he knows how.
The artical starts with the tale of the woman who become a Republican after 911: You could read that as causing her to percieve the world as a more uncertain and threatening place and this triggers a need to make ones environment safe.
I can see easily that the security found in conservatism (small c) can reduce the anxiety provoked by intelerance of uncertainty and would also argue that this is the case with religiousity.
