You don't know that a double standard exists between rats and republicans? The media protected Byrd, often by their silence. It's only when democrats' misdeeds are egregious (Anthony Weiner) that they will toss the democrat under the bus.
If Romney becomes the nominee, all their ammo will be tossed against him, including the cult he is a member of.
“You don’t know that a double standard exists between rats and republicans?”
I’m aware of the double standard, but the arguments of the rats are weakened when the double standards are too obvious. For instance, the democrats were constantly bludgeoning republicans for their supposedly neanderthal tendencies regarding sexual harassment, they really owned that issue. But when their boy Bill Clinton came under fire for it, suddenly most of the hysteria died down very quickly, and most of the corporate training and seminars on sexual harassment seemed to disappear almost overnight.
