What if they get good at faking memos?

Besides the usual typos and misspellings, the latest too-good-to-check memo has this going for it:

What, then, was the evidence for the claim that it was created and distributed by Republicans? As far as the public record shows: There is none. On the contrary, the only published report identifying the purveyors of the memo on March 17 states that they were Democrats.

I guess they don't need to be good forgers. MSM seems to take the bait every time.
