I think Cruz and Rubio are done for this cycle but they are young guys who will be at it in the future.
It would be good to get this resolved this year, if that is possible.
It should be resolved this year. Rubio is not a Natural Born citizen. Read the Constitution. Any judge should easily be able to rule against Rubio's eligibility. Of course one has to assume that the judge understands the English language. That could be a problem considering the recent SCOTUS rulings.
