Why aren't they called Lies anymore?

The front page article of the Washington Post leads :

As Campaign Heats Up, Untruths Can Become Facts Before They're Undone

So why can't we just call them lies anymore? Is it just because they're Republicans? How one-sided is that? I propose the headline: Liar, Liars and the Stinking Lies They Tell.
Let's make it more point-0f-fact and call a spade a spade and stop ruminating on silly turns of phrase like "putting lipstick on a pig."

Can't we just bring back the common sense?
