That conservatives know man is imperfect.To seek for utopia is to end in disaster, the conservative says: we are not made for perfect things. All that we reasonably can expect is a tolerably ordered, just, and free society, in which some evils, maladjustments, and suffering will continue to lurk.
And yet, too many conservatives seem to seek and expect perfection in their candidates and elected officials. Any deviation is castigated. In that respect we do demand our own views of "perfection".
It would seem just as likely that the moderate wing of the party seeks perfection, as evidenced by their jettisoning of conservative candidates who express points of view offensive to them.
