Is snopes politically biased

I have finally come to the conclusion that snopes is not impartial, factual, neutral or unbiased where Oback Obama is concerned. I have really tried to be neutral myself but have to face the fact that I have never read even potentially critical response of any of snopes responses to the accusations or questions about Obama's viewpoints, behaviors, or background. No matter how much Obama might be admired by someone, he is not a perfect person any more than I - or you are.
