And lying through his teeth. If this question were so settled, there would be no debate, just as there is no debate on the age one must be to run for president.
Cruz will produce his CRBA in the next few days. The public will accept his assertion that this settles the issue conclusively.
I take it that you have no experience in politics. Throwing accusations out and forcing your opponent on the defense prevents them from going on offense. This is why the GOPe is so fluxomed about Trump, he refuses to go on defense. Cruz does NOT need to address this, because he has. If the dems want to file suit, then the SC and ONLY the SC could resolve it. Cruz cannot go directly to the SC and ask for a declatory judgement.
