Everyone should read these two tweets before the schadenfreude euphoria goes to your head. I've been saying it in the other Dominion threads but it bears repeating: Suits involving defamation against a public figure are very very very hard to prove in the United States. Ken says it right out there, you have to prove in court that Powell either knowingly lied or knowingly disregarded the truth (with receipts to back you up) so that the defamation rises to the legal standard of "actual malice".
Dominion certainly has a chance here, moreso than a lot of other defamation cases (cough cough
Vic Mignogna cough cough), but it is still a very tough road to walk.
