No they aren't. There's no way to get that in a civil lawsuit. In fact there is no way to vacate the election, period. All they can do is ask for damages, and so far as we know there's no proof to any of the claims so they won't get that.
What they are trying to do is use it as PR in an election year, and to get discovery.
Yes, they are trying to vacate the election results. If they win the suit - they’ll press to delegitimize the election and demand Trump and the GOP stand down for stealing the election.
This is calling for civil war.
This is a damn dangerous game they’re playing but it’s been done before... Venezuela, Cuba, China, Russia, Germany... how do you think these countries governments were overturned within the span of a few years?
By this kind of chicanery.
