If someone intends to keep Cruze off the ballot in a state or states they need to get busy with the lawsuit (s) or challege (s). Ballots will be printed very soon in a majority of the states based on the dates for deadlines for a request for an absentee ballot.
Also I expect that sort of challenge would be settled quickly because it would be in the individual states’ best interest to do so.
They won’t know the actual nominees until after the conventions, so they can’t print until after early Aug 2016. Right?
