What the heck happened? Had Cruz's site already been hacked? Nope, it turns out that he's never owned this site.
It appears, according to the Whois record for his domain, that "Cruz's" domain is registered with GoDaddy. Its owner is hidden by the company Domains By Proxy. This business, owned by GoDaddy founder Bob Parsons, specializes in hiding domain name owners' real identities from researchers.
Given his political opinion, and that the Texan (by way of Canada) Cruz didn't get the site during his Senate run, it seems unlikely that Senator Cruz will be using this site anytime soon. Candidate Cruz's real websites are his U.S. Senate site and his campaign site, TedCruz.org.
So, if you're thinking your little boy or girl might be president one day, register their domain name now! By the time they're old enough to vote, never mind run, it may be too late for them to get their best site.
