Yipes, already this monster has gone to 5 pages in length.
As for myself, the question only becomes important if you fail to nail down what a skeptic is.
If a skeptic is a position, with a series of litmus tests ('do you believe in bigfoot? if so, you're not a skeptic' 'do you believe in accupuncture? if so, you're not a skeptic' and so forth), then you can easily toss 'do you believe in God' on there, and promptly toss out anyone who says yes.
Problem is, skepticim isn't supposed to be about a position, it's supposed to be about a set of methods for finding knowledge. If you start tossing people because of their beliefs, then you are doing exactly what out opponents have accused us of all along: turned scepticism into a belief system.
Now, I've always viewed a 'skeptic' as someone who espouses and promotes skepticism. As I've stated before, everyone on the planet uses skepticism at one time or another. So, with that, can a skeptic believe in God? Heck yeah. He or she could even believe in Bigfoot; the evidence just might be convincing enough (or them, but not for most of us, I warrent).
The question of 'can a skeptic believe in suchandsuch' only leads to dogma, which I thought we were not about. I hope that most of us aren't about it.
Besides, its completely the wrong question. It's not "can a skeptic believe in God"; a better question is "can a skeptic be consistent in his or skepticism and still be a theist". The Deists are not the enemy of science here folks; most of our problems are coming from those who are enforcing their religious will on us with bans on stem cell research, creationism in the schools, death threats over intellectual curiousity and research, etc ad infinitim ad nausiam.
