The deadline for getting your name on the ballot for the PRIMARIES has already passed in most states. The ballots have to be printed in time for military and other absentee ballots to be mailed. The deadline to request an absentee ballot in most states is some date specific in February, March and April. So if someone wishes to challenge Cruze’s eligibility to be on the ballot it will have to he done very soon.
Filing suit after Cruze is nominated would be a lot more complicated. Just getting a court to agree you have standing could take years.
That simply cannot be right. They don’t know who the presidential nominee will even be for either party. Probably Hillary for the dems, but who knows. And there’s no idea with the republicans, although Trump is in the lead.
If you’re talking about the primary, then fine. But I’m not talking about the primary. The challenges will wait to see if Cruz or Rubio wins the nomination.
And even then, a convention does have final say. They ‘can’ change things.
