That's obviously ridiculous. Our commitment should be to Truth first - above any candidate. False allegations are just as reprehensible as attempts to excuse or cover-up wrongdoing.
I for one will withhold judgment until the truth comes out. If there is no confirmation of the allegations, then they must not be accepted. But, heaven forbid, they are confirmed, then we must not keep our heads in the sand.
Like Obama's birth certificate? Don't hold your breath. I doubt we'll ever know the truth in our lifetimes. I use the strategy of thinking who benefits most from these tactics. I take a look at how Obama won his Senate seat, and draw my own conclusions. But if you always believe there's fire when you see smoke, go ahead.
