Exactly, and bringing it up serves no purpose other than to keep the topic alive and raise doubt in people's minds. A lot of people will look at these discussions and think "If he's natural born, why do they keep bringing it up?"
Stop talking about it!
A reason that I see to keep talking about it is to prepare for the inevitable lawsuits that are to come. More than 200 lawsuits were filed challenging Obama’s eligibility. Preparations are already underway among the hardest of the hard core “birthers” to challenge Senator Cruz and Senator Rubio (and others like Rick Santorum’s Italian immigrant father and Rick’s dual Italian-U.S.citizenship at birth).
One of the early Obama eligibility challengers was Commander Charles Kirchner [USN Ret.]. Kirchner v Obama went all the way to the Supreme Court of the United States. Kirchner is going after all candidates not born in the US to two born in the USA parents.

Because Cruz does not fit the original and continuing, at least until the last dozen years, the definition of “natural born.” He is, however, eligibble as that clause of the Constitution has been repealed by the Democrat Party and by Conservatives who believe that it doesn’t apply to them.I am not being bitteror satirical. That is just how it is. Cruz and Walker are the two stars of the Conservativism.
